    Capas en CSS: Guía Completa para Dominar la Regla @layer y Controlar la Especificidad
    Introducción: ¿Qué son las Capas de Cascada en CSS? Las capas de cascada (cascade layers) en CSS han sido introducidas para resolver uno de los problemas más complejos y persistentes en la escritura de estilos: los conflictos de especificidad. En este artículo exploraremos cuál es exactamente ese problema y cómo la regla @layer nos ofrece una solución eficaz y moderna. La regla @layer permite declarar estas capas de cascada, que funcionan de forma análoga a las capas en editores gráficos como Photoshop o GIMP: cada capa es un grupo independiente, pero en lugar de imágenes, gestionamos reglas CSS. El objetivo principal es claro: Organizar mejor el código. Evitar los problemas clásicos de especificidad. Reducir la necesidad de usar !important o sobreescribir selectores complejos. …  ( 10 min )

    Dica de TI: O que são tipos de dados?
    Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Um tipo de dados representa as características de uma variável que determina que tipo de dados ela pode conter. Exemplo tipos de dados primitivos: Essas variáveis guardam valores. Exemplo: números, byte, short, int, long, float, double e boolean char. A aplicação guarda o endereço em memória e não o valor em si. Importantes casos são as arrays e os objetos. Exemplos Arrays, Objetos, Classes, String. Os tipos primitivos são predefinidos (já definidos) em Java. Tipos não primitivos são criados pelo programador e não são definidos. Tipos não primitivos podem ser usados para chamar métodos para realizar determinadas operações, enquanto tipos primitivos não podem. Um tipo primitivo sempre tem um valor, enquanto os tipos não primitivos podem ser null. Um tipo primitivo começa com uma letra minúscula, enquanto os tipos não primitivos começam com uma letra maiúscula.

    Sightful's Spacetop Is a Better, More Practical Spatial Computing Experience
    Sightful’s Spacetop for Windows is a $899 bundle (plus a $200/yr subscription after year one) that turns your compatible Intel-powered laptop and Xreal Air 2 Ultra smart glasses into a multi-monitor, spatial-computing workspace. Wired gave it a 9/10, praising its polished software, comfy glasses (with dimming for outdoor use) and the private, ultra-portable productivity it delivers—arguably edging out Apple’s Vision Pro at a fraction of the price. It’s not all sunshine, though: the setup looks a bit dorky, only works on select Intel CPUs for now, saps battery life in a hurry and the glasses’ field of view could be wider. Still, if you’ve been dreaming of carrying your home-office everywhere, Spacetop might finally make it happen.  ( 3 min )

    The concept of a temporary View state in JavaScript
    Greetings to all! In this article, we will talk about a rather unusual topic, information about which for some reason I did not find, although it is quite useful in modern JavaScript frameworks and libraries for creating user interfaces, because, in some cases, applying the concept can help speed up work with the DOM several times. The name is conditional, but the essence is important. The term "usual state" refers to data that is saved directly due to the state managers, or due to the internal functionality of the framework or library. An example of the state in Vue.js: createApp({ setup() { return { count:ref(0); }; }, template: ` Click! Clicks: {{ count }} `, }).mount("#app"); In this case, …  ( 6 min )
    Marc Andreessen Says AI Can't Replace His Job: VC Tech Investing
    Marc Andreessen—the “MarcGPT” behind a16z and the first popular web browser—loves AI so much he calls it “our Philosopher’s Stone” and has plowed cash into OpenAI and Elon Musk’s xAI.

    Dissecting the HTTP Request — Line by Line
    Dissecting the HTTP Request — Line by Line Demystifying HTTP for Web Developers, Part 2 In Part 1 of this series, we traced the full journey of an HTTP request — from typing a URL in the browser, through DNS resolution and TCP handshakes, all the way to receiving the server’s response. But understanding the path a request travels is only half the story. To truly master HTTP, we now need to dissect the payload that actually moves across the wire: the HTTP request itself. Every interaction between a web client and a server begins with a carefully structured message — the request. It may look simple on the surface, but every line, header, and byte in that request carries meaning. If you’re building serious web applications, APIs, or even debugging flaky integrations, you can’t a…  ( 13 min )

    Implementing the Royal Game of Ur using Mistral's Codestral
    In this post, I test how Mistral's Codestral, the model specifically trained to generate code, compares to the Mistral's Le Chat, the general AI chat. For my experiment, I use the Royal Game of Ur, an ancient Babylonian game that I already implemented using Le Chat. At least in my experiment, Codestral's performance is, frankly, disappointing. While it produces code that follows a certain architecture, the code quality is low. In fact, it even generates a statement of the form a = foo() where a has a different type from what foo() returns.

    Cloud-Native: Are You Paying for What You Use… or for What You Provision?
    Everyone’s in the cloud. Stacks have migrated. Infrastructure is containerized. CI/CD pipelines are green.

    EventTarget - CustomEvent | components communication in React - part Three
    In the first and second parts, we focused on creating two different patterns for handling data flow in React. EventTarget is the foundation of the browser’s event system. addEventListener, removeEventListener, and dispatchEvent. Many core Web APIs including DOM elements like , , , as well as document and window inherit from EventTarget. When we attach an event handler to a DOM element—like in the picture above—we’re actually subscribing to that element through one of its event channels. In this case: The button is the publisher (or emitter) The callback function passed to addEventListener is the subscriber (or listener) So when a user clicks the button, the button emits a 'click' event, and all registered listeners for that event type are notified and executed. So with…  ( 5 min )
    Beyond the Bugs: How Software Testing Fuels Innovation 🚀
    I’m a product owner, guiding a team building a collaboration app for remote workers. Last quarter, we rushed a feature—real-time document editing—without thorough testing. It launched buggy, crashing for users with large files. Clients churned, and our team’s morale tanked. Testing isn’t just about finding bugs—it’s about enabling us to push boundaries. In April 2025, software testing drives innovation, giving us confidence to experiment and deliver bold features. This isn’t a technical deep-dive or buzzword parade—it’s my story of how testing fuels progress, shared for professionals who want to innovate without breaking things. Testing is often seen as a bug hunt, but it’s so much more. It’s the engine that powers bold ideas, protects user trust, and keeps teams moving fast. Our app’s cra…  ( 7 min )
    The Spirit of Plan 9 on the Web
    If you go back to the first talk ever given on webhooks, it opens on the command-line. Specifically the Unix shell, focusing on one of its defining features: pipes. The idea was that pipes brought a new level of compositionality to programs, and webhooks could bring a new level of compositionality to web apps. Perhaps you could say I was trying to bring the spirit of Unix to the web. With this last release of Wanix, I'm at it again. This time with the successor to Unix, a little known operating system called Plan 9 from Bell Labs. Plan 9 has been on my mind for quite a while. In fact, around the time of that first talk on webhooks, the team behind Unix and Plan 9 was being re-assembled to create the Go programming language. I pretty instantly fell in love with the Go worldview, which turns…  ( 5 min )

    #6 DP: Decorator
    O que é o Padrão Decorator? O Decorator é um padrão de projeto estrutural que permite adicionar comportamentos adicionais a um objeto de forma dinâmica. Ele permite que você encadeie funcionalidades (como validação, construção, logging e outras) em um fluxo sequencial, sem modificar a estrutura original da classe. Isso possibilita adicionar ou remover comportamentos com facilidade, mantendo o código mais flexível e desacoplado. Em resumo, o Decorator cria uma cadeia de responsabilidades onde cada classe pode adicionar sua funcionalidade à sequência, sem afetar as outras. Imagina que você precisa realizar várias validações (como validar o usuário, estoque e status), mas não quer que elas fiquem fortemente acopladas. O objetivo é poder adicionar, remover ou reorganizar facilmente as valida…  ( 4 min )

    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}'
    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}' TypeScript has quickly become a favorite tool for developers building scalable and maintainable JavaScript applications. At its core, TypeScript is a superset of JavaScript—it builds upon JavaScript by introducing static typing, as well as other modern programming concepts that make your code safer and easier to manage. Static typing means that developers can explicitly define the types of data (like string, number, or boolean) their variables and functions work with, catching potential errors during development instead of at runtime. If you're new to TypeScript, or want to sharpen your existing skills, consider following our blog or using advanced learning tools like gpteach.us to explore how modern AI tools ca…  ( 6 min )
    TS2333: 'this' cannot be referenced in constructor arguments
    TS2333: 'this' cannot be referenced in constructor arguments TypeScript is a statically-typed superset of JavaScript designed to add type safety and developer-friendly features to JavaScript code. A "superset" means that TypeScript builds on JavaScript by adding new functionalities, while still allowing you to write plain JavaScript. One of its most powerful features is the introduction of types (a system to define constraints on the structure of your data). This is immensely beneficial when working in large projects to detect errors at compile time, ensuring your codebase is reliable and maintainable. Types in TypeScript help us describe the shape of an object, function, or data. For instance, when you define a function or an object, you can explicitly specify what inputs it expects and…  ( 6 min )
    TS2332: 'this' cannot be referenced in current location
    TS2332: 'this' cannot be referenced in current location TypeScript is a popular open-source programming language developed by Microsoft. It’s often referred to as a superset of JavaScript because it builds on JavaScript by adding optional static types. These types allow developers to define the structure and behavior of variables, functions, and objects, making programs easier to debug and maintain. TypeScript compiles to plain JavaScript for execution, which means it seamlessly integrates with existing JavaScript projects. Simply put, types in TypeScript are what allow you to specify the kind of data a variable or function should handle. For instance, you can declare that a variable must always hold a number, a string, or a custom structure (like objects or classes). By catching errors …  ( 6 min )
    TS2331: 'this' cannot be referenced in a module or namespace body
    TS2331: 'this' cannot be referenced in a module or namespace body TypeScript is a powerful language that builds upon JavaScript by adding optional static typing. By introducing "types" (representations of data such as strings, numbers, and objects, among others), TypeScript allows developers to write more predictable and maintainable code. It’s often referred to as a superset (a language that extends the features of another) of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. A major advantage of TypeScript is its ability to catch errors during development, before the code is executed. However, while it enhances safety and boosts productivity, developers may sometimes encounter compiler errors that seem confusing at first. One such error is TS2331: 'this' ca…  ( 5 min )
    TS2329: Index signature for type '{0}' is missing in type '{1}'
    TS2329: Index signature for type '{0}' is missing in type '{1}' TypeScript is a strongly typed superset of JavaScript. This means that it builds on top of JavaScript by adding an optional type system (a way to define and enforce the kinds of data being used in your code). TypeScript is a powerful language designed to catch errors early during development, making your JavaScript codebases more robust and maintainable. In TypeScript, "types" play a central role. A type defines the shape of data, specifying what kind of data will be stored, its expected structure, and the operations you can perform on it. For example, string, number, boolean, and object are common types used in TypeScript. Types ensure that your code only operates on the data it was designed to handle; if it doesn’t match t…  ( 6 min )
    TS1433: Decorators may not be applied to 'this' parameters
    TS1433: Decorators may not be applied to 'this' parameters TypeScript is a strongly-typed programming language that builds on JavaScript by adding static types (data classifications, such as string or number). TypeScript helps developers write safer, more predictable code because it allows the compiler to catch potential bugs during the development process, before the code is executed. Essentially, TypeScript acts as a typed superset of JavaScript, meaning it includes all the features of JavaScript while adding new functionalities, mainly focused on type safety.

    Understanding the Regulatory Landscape for Tokenized U.S. Equities
    Introduction to Tokenization In recent years, the world of finance has seen significant advancements, especially with the introduction of blockchain technology. One of the most exciting developments in this space is the concept of tokenization, particularly the tokenization of U.S. equities (stocks). But what exactly does tokenization mean, and why is it so important for U.S. equities? What is Tokenization? Tokenization refers to the process of converting ownership of an asset, such as stocks, real estate, or artwork, into a digital token on a blockchain. This token represents ownership or a portion of ownership of the underlying asset. In the case of U.S. equities, tokenization means turning traditional company shares into digital tokens that are recorded on a blockchain ledger. Blockcha…  ( 8 min )
    🚀 Turning Videos into Interactive Courses with AI
    How I built VidSabio.com by combining multiple LLMs into a robust processing pipeline I recently launched VidSabio, a platform that transforms ordinary videos into structured, interactive learning experiences — automatically. 🎥➡️📚 But this didn’t come together overnight. At first, I thought a single LLM could handle everything: analyze the video, transcribe it, generate quizzes, build a course. Easy, right? Wrong. It turned out the real breakthrough came when I stopped looking for one model to do it all — and instead built a pipeline of specialized steps, each powered by the best tool for that specific task. Here’s the high-level breakdown of how it works: User uploads a video Video is processed through a multi-step pipeline: Frame extraction (FFmpeg) Audio transcription (Google Speech-to-Text) Visual analysis (Gemini / GPT-4 Vision) Content summarization + topic generation (Gemini Pro) Course structure generation (GPT-4) Interactivity injection (quizzes, accordions, etc.) Final course can be edited and exported as SCORM or HTML This is all built using Vue 3, Firebase, and various LLMs (OpenAI + Gemini) stitched together through Cloud Functions. By distributing the heavy lifting across multiple LLMs and APIs, I was able to: Improve accuracy Scale more efficiently Debug and retry isolated steps Customize outputs based on step-level feedback Frontend: Vue 3 + Tailwind Backend: Firebase Functions + Firestore + Storage AI: GPT-4.1, Gemini Pro, Whisper, Google Speech-to-Text Analytics: PostHog Export: SCORM, HTML Here's a stylized diagram of the flow: (Insert your HappyAlien-styled image here) This was built with plenty of detours, dead ends, and "aha" moments. If you're building with LLMs, I encourage you to explore multi-model orchestration — it might be the key to your next breakthrough.

    🎨 Introducing GitVisualize – Turn Any GitHub README into AI-Generated Art
    Hey DEV community! I just launched a side project I’ve been tinkering with: GitVisualize It lets you paste in any public GitHub repo URL, and it’ll generate a visual representation of that project using OpenAI’s gpt-image-1 model — all based on the repo’s README content. Takes a GitHub repo URL Pulls the README Feeds it to an AI image model Displays the generated image alongside project metadata Adds it to a public gallery You can even choose the image style you want: Conceptual & Techy Infographic Abstract & Minimalist Direct & Clear It’s built with Vue 3 + Tailwind, uses Supabase for storage and data, and everything runs through a lightweight backend on Render. I love browsing GitHub, and I wondered: “What would this project look like if it were a picture?” So I built GitVisualize as a fun experiment in combining AI, dev culture, and a bit of creativity. Some of the results are surprisingly expressive.

    Leading with Conviction, Listening with an Open Mind
    A piece of feedback that reshaped how I think about conviction, consensus, and presence when you're the most senior person in the room. Originally published at mustafatorun.me A few years ago, I wrote a design document outlining a few different options. It was for a group more experienced than me—not in the domain, but in the industry. I knew the problem well. I had done the work. But still, I softened my position. I showed the tradeoffs, invited discussion, and held back from saying with confidence, “This is the direction I believe we should take.” In a pre-review, someone I trusted — someone more experienced than me — called it out. The document lacked conviction. It read like I was asking the group to decide for me. They reminded me that I was the expert in this domain — not them. What …  ( 4 min )

    What is Tailgating?
    In the world of corporate security, not all breaches involve sophisticated hacking tools—some simply walk through the front door. Tailgating, a subtle yet dangerous form of intrusion, happens when an unauthorized person gains access to a restricted area by following closely behind someone who is authorized. It's a tactic that relies less on technology and more on exploiting human behavior. Attackers often masquerade as employees, contractors, or delivery workers. They may carry packages, wear uniforms, or claim to have forgotten their access badge—all to lower suspicion. Once inside, these individuals can do far more than just roam the premises. They might access critical systems, plant malicious software, or steal sensitive equipment. Pretending to be a colleague and asking someone to hol…  ( 4 min )

    schema-env v2.1: Now with Pluggable Validation Adapters (Joi, Yup, Your Own!)
    The Pain of Missing Env Vars We've all been there: deploying a Node.js application only to have it crash immediately (or worse, subtly misbehave) because a crucial environment variable like DATABASE_URL was missing, empty, or malformed. Debugging configuration issues after deployment is frustrating and time-consuming. Manually checking process.env properties everywhere is tedious and error-prone. What if you could guarantee your application's required environment variables are present and valid before any of your core application logic runs?

    The Day I Discovered enumerate()
    It was a regular evening debug session. My code was working, but something about it just felt off. I was looping over a list—like always. for i in range(len(my_list)): value = my_list[i] # Do something with value and i Nothing wrong, right? Except... I was starting to hate reading my own code. range(len(...)). Too much manual indexing. 👀 The Realization for i, value in enumerate(my_list): # Do something with i and value Wait... what? No range(len(...))? No messy indexing? ✅ Cleaner 🧠 Why it works: enumerate() is a built-in Python function that returns both the index and the value of items in an iterable—in one shot. It’s like your loop suddenly gained superpowers. 💡 Bonus Tip: for i, val in enumerate(my_list, start=1): print(f"Item {i}: {val}") Perfect for user-facing counters. No more +1 hacks. 🚫 Never Again... No more range(len(...)) unless I really need it. Now, it’s all enumerate(), all day. ✨ Moral of the Story: If you're reaching for range(len(...)), stop and ask yourself— What would enumerate() do? 😎  ( 3 min )
    How to Access Fields with Spaces in Lumerical FDTD Farfield Data?
    When working with Lumerical FDTD simulations, access to specific fields from the results of a far-field projection monitor might sometimes be challenging, especially when it comes to field names with spaces. In your case, you're able to access standard fields like E2 and Es easily: farfield = getresult("monitor", "farfield"); E2 = farfield.E2; Es = farfield.Es; However, when it comes to the field "Ep vs angle", an error arises. This can happen due to the space in the field name, making direct access using dot notation invalid. Understanding the Structure of the Farfield Object The farfield object typically contains several fields, including E2, Es, and multiple arrays or matrices concerning angles and wavelengths. The fields you can access directly using dot notation are designed to be id…  ( 4 min )
    be careful with return values in go
    About I was writing a program in go, where I was calling a function,which takes an existing slice, modifies it and returns it back.Then I had a print statement that prints that slice. did not assign the return value of the function call,which is the modified slice,to the old slice variable.In Rust or in some other languages,the compiler will yell at us if we leave the return values of a function call without assigning them. go compiler will not give an error if we leave return values of a function call.

    RDMA(Remote Direct Memory Access)는 네트워크를 통해 서버 간에 CPU 개입 없이 메모리를 직접 읽고 쓰는 기술이다. 주로 고성능 컴퓨팅(HPC), 대규모 데이터 처리, AI/ML 분산 학습 환경 등에서 낮은 지연 시간과 높은 대역폭을 제공하기 때문에 많이 사용한다. 1. RDMA의 기본 개념 일반적인 네트워크 통신 방식에서는 데이터를 전송하려면 CPU가 메모리에서 데이터를 읽고, 네트워크 인터페이스 카드(NIC)로 복사한다. 이 복사한 데이터를 네트워크를 통해 데이터를 보내고, 수신 측에서도 CPU가 데이터를 NIC에서 메모리로 복사한다. 이 과정에서 CPU, 커널, 복사 작업 등이 개입되어 지연(latency)과 CPU 오버헤드가 큰 현상이 발생한다. 반면, RDMA는, CPU나 운영체제(OS) 커널의 개입 없이, 원격 시스템의 메모리에 직접 읽기(read) 또는 쓰기(write) 작업을 수행한다. 다시 말해, 데이터가 직접 메모리에서 메모리로 이동한다. 2. RDMA가 동작하는 방식 (1) 메모리 등록 (Memory Registration) 송신자와 수신자 모두 RDMA NIC(HCA: Host Channel Adapter)를 사용함. RDMA를 사용하기 위해서는 사용할 메모리 영역을 등록(pinning)해야 함. 이 과정에서 해당 메모리는 물리 메모리에 고정되고 커널이 RDMA NIC에 메모리 주소를 알려줌. (2) Queue Pair 생성 RDMA 통신은 QP(Queue Pair)라는 구조를 통해 이루어짐. QP는 Send Queue와 Receive Queue로 구성…  ( 4 min )

    The Scraping Story: The Car Repair Team
    The Scraper: The Collector of Car Parts Each day, the Scraper ventured out, gathering essential tools—brake pads, spark plugs, and oil filters—meticulously putting them in his storage room. This storage room, filled with parts, was like a database, organizing all the precious data he gathered from various sources. For instance, one day, the Scraper found a batch of brake pads. He cataloged the details, from brand to condition, and stored it safely. This was like collecting the latest prices from websites, storing them in a file for future use. The Backend Guy: The Toolbox Handler Whenever the mechanic—the Frontend—needed a specific tool, they would call out, “I need a 10mm wrench!” The Backend Guy, standing by the toolbox, would find the correct tool and hand it over with precision. He didn't fix the car himself, but he made sure the mechanic had exactly what was needed at the right time. Just like that, the Backend Guy managed the storage of all the data and ensured it was always ready when the Frontend needed it. When the mechanic asked for the current price of the Euro in Toman, the Backend would retrieve that data and send it in a neat package—a JSON response—ready to be used. The Frontend Mechanic: The User Interface When the mechanic needed a part, they'd shout, "I need a 10mm wrench!" The Backend Guy would respond, handing over the tool, and the Frontend Mechanic would get to work. The mechanic didn’t care how the part got there, as long as it was the right one. In the same way, the Frontend Mechanic used the data provided by the Backend to create an amazing display for the car's dashboard. They made sure the car (or website) looked stunning, with neatly organized parts (like the prices) and a smooth-running engine (user interface). Whether it was showing prices in a nice table or providing a simple, user-friendly experience, the Frontend Mechanic made sure everything was visually appealing and functional.  ( 4 min )

    IaCConf 2025: Why Infrastructure as Code deserves its own conference
    Infrastructure as Code (IaC) has come a long way since its beginnings. What started as spinning up cloud resources has now grown into a full-blown ecosystem with a very engaged community. IaC on its own can add a lot of complexity to your processes and cause more issues, but combined with governance, compliance, security, deployment strategies, self-service, it easily becomes the fuel your delivery engine needs. This year, IaCConf debuts as a virtual event by bringing together this community, and it’s shaping up to be one of the most relevant and practical events in the space. Unlike broader DevOps/SRE or cloud-native events, IACConf is focused on the challenges and innovations around defining infrastructure as code. That means the content goes deeper, the conversations are more relevant, and the takeaways are directly applicable to your processes. There will be sessions on: Getting started with IaC Managing IaC at scale across teams and environments (using OpenTofu, Terraform, Ansible, Crossplane, and others) Platform Engineering and IaC How IaC impacts your maturity AI in IaC And that’s just scratching the surface. Check out the full agenda here. One of the things I appreciate most about this conference is that it’s not about product pitches or high-level fluff. Practitioners share what worked, what broke, and how they improved. Whether you are just starting out, are in the trenches, or shaping platform strategy, there’s something for you here. On another note, I’m also excited to contribute to this year’s lineup with a session on Getting Started with IaC, together with my colleague Emin Alemdar. But honestly, I’m just as excited to learn and to connect with others working through the same challenges. The event will be on Thu, May 15, 2025 @ 11:00am EDT, so don’t forget to register here.

    How to Properly Implement mat-list and mat-divider in Angular?
    Introduction When developing Angular applications, particularly with Angular Material, you might encounter issues regarding the mat-list and mat-divider components. Many developers wonder whether to use ngFor inside the mat-list or the mat-list-item and how to correctly place the mat-divider. Let’s delve into this topic to clarify which method is best. Why This Issue Arises The confusion around where to implement ngFor and the positioning of mat-divider often stems from how Angular handles component rendering. Using ngFor within the mat-list means that each item is rendered as part of the list itself; thus, the dividers are less likely to show correctly if their placement isn’t considered carefully. Conversely, applying ngFor to mat-list-item makes each list item independent and potentiall…  ( 4 min )

    What is a Proxy Firewall and How Does It Work?
    A proxy firewall, often referred to as an application-layer or gateway firewall, acts as an intermediary between a user’s system and external servers. Instead of allowing direct communication, it processes and forwards requests on behalf of users. This not only hides internal network details from outsiders but also allows the firewall to thoroughly inspect data before it reaches its destination. Unlike traditional firewalls that operate primarily at the network or transport layer, proxy firewalls operate at the application layer. They intercept requests, evaluate the content, and relay approved traffic. This additional layer of inspection allows for more granular control, helping detect threats embedded in seemingly legitimate requests—such as malware hidden in web traffic or email attachm…  ( 4 min )

    LLM 훈련/추론 시 총 메모리 크기는?
    국내 기업들을 방문해서 AI 인프라 관련 분들을 만나면, 가장 많이 물어보는 질문들 중 하나가 LLM 추론 시 메모리 크기는 얼마나 되는 것인 가이다. 아무래도내부에 가진 서버를 그대로 사용할 것인가? 아니면 신규로 서버를 구매할 것인가?에 대해 LLM을 동작 시킬 때 총 메모리 용량이 얼마나 되는 지 궁금해서 일 것이다. 예를 들어, meta-llama/Meta-Llama-3-8B-Instruct에서 훈련(Training) 또는 추론(Inference)할 때, Tensor Type으로 BF16 이면 메모리 크기는 얼마이며, 몇 장의 GPU를 사용해야 하는가에 대해 묻는다면, 어떻게 답변을 해야 하는지 알아 볼 것이다 메모리 사용량 개략적 계산 = (모델 파라미터 * 2) + 파라미터의 2 - 3배 BF16(bfloat16)은 FP16과 마찬가지로 16비트 정밀도를 사용하므로, 기본적으로 모델 파라미터*자체가 차지하는 메모리는 FP16 대비 큰 차이가 없음. AdamW 와 같은 옵티마이저 상태나 그래디언트, 중간 활성화 (activations) 등으로 인해 실제 요구되는 메모리는 2~3배 가량 될 수 있음. 계산식: (16 * 2) + (16GB * 2 or 16GB * 3) = 32GB + (32 or 48 )GB = 64 or 80 GB BF16 타입으로 풀 파인튜닝(Full fine-tuning)시 단일 GPU으로는 최소 40GB 이상, 안정적인 배치 크기 확보를 위해서는 A100/H100 80GB급이 1장이 권장 80GB H100 1장으로 분산 학습을 활용해도 충분히 학습이 가능함.…  ( 4 min )
    🧠🚀Open project for discussion: OS Against Porn - Anyone interested in implementing it?🧩
    Hello, I have an ambitious technical idea that I hope to share with the community of developers and cybersecurity specialists: Given the widespread prevalence of pornographic content online, and the difficulty of controlling it through traditional blocking or weak censorship tools, I've come up with a new system: 🔐 An "ethical operating system" (for smart devices – such as Android, iOS, and Windows) built from the ground up on the principle of: "Completely blocking any type of pornographic content, whether visual or textual, whether on websites, apps, search engines, or social networks." 💡 Key features of the idea: Its protection cannot be hacked or changed (such as the inability to install an alternative system). It can be installed on children's devices, school devices, or even the devices of adults who want to protect themselves. It doesn't rely solely on blocking a specific site, but rather on real-time content analysis. A clean app store and a clean built-in search engine. 🧱 Technically: Or as a distribution for children, schools, or conservative environments. Or even as a layer of security added to existing systems (e.g., Android). 🎯 The goal is not to impose censorship, but rather to provide a safe, ethical, and educational alternative. 🤝 I'm looking for: Interested programmers. Note that I'm only 16 years old. The goal is to find someone who will embrace this idea. Suggestions for improving the idea. Any technical or community support is possible. Do you think this type of system could make a real difference? opensource privacy cybersecurity idea  ( 3 min )

    Interviewing Software Developers: From Junior to Architect in a Single Programming Task
    Over the years, I’ve interviewed around 100 software developers at Google and roughly the same number across my own companies. One thing has become very clear: Resumes don’t work. They’re too noisy. You get flooded with titles, buzzwords, and irrelevant project summaries. So I distilled everything down to one single task. One prompt I can give to anyone — junior or architect — and instantly get a signal. The task? Write a library that calculates the sum of a vector of values. That’s it. No extra requirements. The beauty is that it looks trivial — but the depth reveals itself as the candidate explores edge cases, generalization, scalability, performance, and design.

    What Is the Role Of Delegates in Objective-c in 2025?
    Objective-C has long been a mainstay in the development of applications for iOS and macOS. Despite the rise of Swift, Objective-C remains a relevant and powerful language, particularly for maintaining legacy code and integrating with newer Swift code bases. As we move into 2025, understanding core patterns like delegation continues to be vital for developers working with Objective-C. Delegation is a design pattern used in Objective-C to pass messages between objects and to provide a mechanism for customization of behavior. It allows one object to delegate tasks to another, enabling a clear separation of responsibilities and enhancing the modularity of applications. Typically, a delegate object implements methods from a protocol to respond to certain events or actions occurring in the deleg…  ( 4 min )
    Rust 101: the fundamentals

    Replacing Lambda Triggers with EventBridge in S3-to-Glue Workflows
    In one of our production data platforms, we used Lambda functions to trigger AWS Glue jobs every time a file landed in an S3 folder. That setup worked fine when there were only two or three data sources. But as the system expanded to support more than 10 folders, it required deploying and maintaining an equal number of nearly identical Lambda functions, each wired to specific prefixes and jobs. The architecture became increasingly brittle and harder to manage. This post outlines how that structure was replaced using EventBridge, with prefix-based filtering and direct Glue job targets. No Lambda. No maintenance overhead. Using S3 events to trigger Lambda comes with several limitations: A single Lambda function can’t be mapped to multiple S3 prefixes Each one requires separate deploymen…  ( 5 min )
    Encapsulation
    To Understand Encapsulation please do check out last post Encapsulation is like a medicine capsule: the outer shell hides the complex ingredient inside, delivering only the intended effect to your body. You don't need to know the chemical makeup to benefit from it. Encapsulation is achieved through the use of access modifiers. Python primarily uses two types of access modifier. Private: Accessible from anywhere. Public: Accessible only within the class. Similarly, in programming, encapsulation wraps data and methods in a class, exposing a simple, controlled interface while keeping the internal details private and secure. Let say I want to make "model" attribute private so that nobody can manipulate the model name. So make it private just add '__model' So, question arise if we can't access attribute but we can access function which include the private attribute. Think of like if we have attribute which you don't want get manipulated then make it private.  ( 3 min )
    How to Fix CarouselView Not Displaying Images in MAUI
    Introduction If you're developing a MAUI application and are facing issues with the CarouselView control not displaying images from an ObservableCollection, you are not alone. This article will address why images may not show up in your CarouselView, even when the same image sources work perfectly with a standard Image control. Understanding CarouselView in MAUI The CarouselView in .NET MAUI is designed to display a collection of items in a swipeable format. Each item can be customized using a DataTemplate, which lets you define how each item appears. Typically, developers use ObservableCollection to bind dynamic data to CarouselView because it notifies the view of changes. However, while you may see indicators appear correctly, images may not load as expected. Common Issues with CarouselV…  ( 4 min )
    What Is the Purpose Of Dynamic Typing in Objective-c?
    Objective-C, a primary programming language used for macOS and iOS development, has always been appreciated for its unique blend of C's efficiency and Smalltalk's dynamism. A critical feature that sets it apart from other languages is its support for **dynamic typing**. This allows for a flexible development process that enhances code modularity and adaptability. But what truly is the purpose of dynamic typing in Objective-C? ## What is Dynamic Typing? Dynamic typing refers to the ability of a programming language to determine the type of an object at runtime, rather than during compile-time. This contrasts with static typing, where the type of an object is known and enforced during compilation. In Objective-C, this means you do not have to specify the class type of an object, providing …  ( 4 min )
    Using Tailwind JIT Mode for Faster Development
    If you're still not using Tailwind CSS JIT (Just-in-Time) mode in your development workflow, you're seriously missing out on one of the biggest productivity boosts Tailwind has ever introduced.

    How to Select N Messages with Sum of Verbosity Less than N?
    Selecting messages with a specified sum of verbosity can be challenging in SQL, especially when the goal is to find all messages where the sum of a specific column stays below a certain threshold. In this case, we want to find messages from a table with a specified verbosity value such that the summed values of verbosity for a given set of rows remain under a specified limit, N. Understanding the Problem In our example, we have a simple table named messages, which contains two columns: id and verbosity. Given the entries: | id | verbosity | |----|-----------| | 1 | 20 | | 2 | 20 | | 3 | 20 | | 4 | 30 | | 5 | 100 | When we wish to choose rows whose sum of verbosity is less than a certain value, say N = 70, we expect to select the rows with ids 1, 2, an…  ( 4 min )

    🧠 State Management in Flutter: Choosing Between Bloc, Riverpod, and Provider
    Flutter makes building beautiful UIs fast and fun — but what happens when your app starts growing? When screens need to react to shared data? That’s when state management becomes essential. In this blog, we'll demystify state management in Flutter and help you decide between Bloc, Riverpod, and Provider — three of the most popular approaches in the Flutter ecosystem. State refers to the data your UI depends on. For example: A counter’s value Whether the user is logged in The list of items in a shopping cart State management is how we keep the UI in sync with the data — especially when multiple widgets care about the same data or when data changes over time. There are two broad types: Local state (e.g., setState inside a single widget) Global/shared state (e.g., auth status, theme, user pre…  ( 5 min )
    Why does fieldClass.getDeclaredFields() return empty in JDK 17?
    Introduction If you're using Java Development Kit (JDK) 17 and noticing that your call to fieldClass.getDeclaredFields() returns an empty array, you're not alone. Many developers have encountered this issue when attempting to retrieve field information from classes in the Java Reflection API. The Java Reflection API is essential for inspecting classes at runtime, allowing developers to gather information about fields, methods, and constructors programmatically. However, certain security restrictions in JDK 17 can lead to unexpected behavior, including the inability to reflectively access declared fields in classes like Field.class from the java.lang.reflect package. Understanding the Root Cause In JDK 17, Java introduced a more robust module system that enforces strong encapsulation by def…  ( 5 min )

    What is fine-tuning in AI?
    Fine-tuning in Artificial Intelligence (AI) refers to the process of taking a pre-trained model and adapting it to a specific task or dataset. Pre-trained models, especially large ones like GPT (from OpenAI) or BERT (from Google), are initially trained on massive datasets using general-purpose data. These models learn a broad understanding of language, patterns, or image features. However, for specialized tasks—like medical diagnosis, legal document analysis, or customer sentiment detection—fine-tuning helps the model learn domain-specific nuances. The process involves continuing the training of the model with a smaller, task-specific dataset while adjusting the model’s weights slightly. This method allows the model to retain its general knowledge while becoming more effective in the target domain. Fine-tuning is far more efficient than training a model from scratch, saving both computational resources and time. There are different levels of fine-tuning. Some approaches adjust only the final layers of the neural network (known as feature extraction), while others allow all layers to be updated (full fine-tuning). Techniques like parameter-efficient fine-tuning (PEFT), such as LoRA (Low-Rank Adaptation), are gaining popularity, especially for large language models, because they minimize the number of parameters updated. Fine-tuning is used in a variety of real-world applications, including chatbots, image generation, fraud detection, and more. It’s especially powerful in scenarios where labeled data is limited but high-quality outputs are essential. With the growth of open-source and pre-trained foundation models, fine-tuning has become a key skill for AI practitioners. To master techniques like fine-tuning, transfer learning, and prompt engineering, enrolling in a Generative AI certification course is highly recommended.  ( 3 min )
    ExpRoot+Log: A Linear and Universal Basis for Function Approximation
    Abstract We introduce a novel numerical method, ExpRoot+Log, for function approximation based on a hybrid linear basis consisting of exponential-square-root, polynomial, and logarithmic components. This method achieves high accuracy across smooth, discontinuous, and rapidly decaying functions while remaining simple, interpretable, and computationally efficient. We show that ExpRoot+Log outperforms classical approaches such as polynomials, splines, Fourier series, and even neural networks in key scenarios, offering a new universal baseline for practical approximation. Introduction Function approximation is fundamental to numerical analysis, physics, machine learning, and signal processing. Classical bases—polynomials, splines, and trigonometric functions—have known limitations, especially near discontinuities or exponential decays. While neural networks provide expressive power, they are complex, opaque, and computationally expensive. We propose a new hybrid basis: This composition handles: All coefficients are learned linearly (e.g., via least-squares), ensuring ultra-fast performance and excellent stability. Numerical Evaluation We tested ExpRoot+Log against standard methods (polynomials, splines, Fourier) across six function types: Sine Exponential decay Step function Gaussian spike Absolute value Composite (piecewise mix) ExpRoot+Log consistently achieved 1–4 orders of magnitude lower error than polynomials or Fourier bases.

    How to Fix Empty Secrets in Azure DevOps Pipeline for .NET 8
    Introduction When working with integration tests in .NET 8, especially when utilizing secrets such as clientId and clientSecret, many developers face issues of empty secret values during pipeline execution. This common problem typically arises in environments like Azure DevOps where secrets must be correctly configured and utilized in the pipeline. Understanding the Problem In your scenario, it seems the Azure DevOps pipeline does not recognize the secrets added to the library asset group, leading to the variables clientId and clientSecret being empty. This can happen due to various reasons such as misconfiguration of variable groups, permissions, or pipeline setup. Let’s break down the potential issues and guide you through resolving them.

    Why Engineering Teams Should Build Their Own AI Coding Agents
    Originally posted at https://qckfx.com/blog/why-engineering-teams-should-build-their-own-ai-coding-agents Imagine walking into an engineering department three years from now. The highest-performing teams will be defined by the proprietary AI systems they've built, customized for their specific codebases, architectural patterns, and business domains. These teams will wield AI as a strategic differentiator, not merely consume it. This is where our industry is clearly headed. As AI increasingly becomes the primary author of code across industries, the strategic advantage will shift from who can write the best code to who can best direct, customize, and optimize AI systems to write that code. The best engineering teams won't achieve these results by simply adopting off-the-shelf AI coding tool…  ( 7 min )
    The code review chaos we faced with GitLab (and what we tried to fix it)
    I've worked in several agile teams as both a developer and lead developer. One particular project sticks in my mind — a team of ten people, dozens of microservices, and a lot of GitLab repositories to manage. During each sprint, we were juggling features across multiple repos. At the same time, we were responsible for reviewing each other’s code. Our typical flow was: Open a merge request (MR) on GitLab Move the related Jira ticket Share the MR link in a Teams channel Move on to the next story When the workload was light, it was manageable. But in busy sprints, reviews piled up quickly. Large MRs got ignored, or rushed through. And tracking what was waiting, what was blocked, or what still needed input? A mess. We experimented with several ideas: Using GitLab labels like needs-review or blocked Adding Jira tags Rotating reviewer ownership by repo each sprint They helped — but they didn’t solve the root problem: lack of visibility and timing. Code reviews were often asynchronous and scattered. We were switching contexts constantly, jumping between repos, and forgetting which contributions needed our attention. We didn’t need more tools — we needed a better way to surface and track reviews. Something that would: Give us a unified view of MRs Let us know what’s ready to merge, what’s waiting, and what’s blocked Respect our flow, instead of interrupting it That’s when I started working on a side project, aiming to solve this specific pain point. That side project became Bellugo — a contribution tracker designed to help teams stay on top of reviews across repositories without the chaos. It’s still a work in progress, but if this resonates with your team, I’d love for you to check out the landing page and maybe join the private beta waitlist.  ( 4 min )
    How to Replace Empty Anchor Tags with IDs in HTML Files?

    Let's Encrypt DNS Challenge with Traefik and AWS Route 53
    So, you're self-hosting awesome apps like Jellyfin, Home Assistant, or your personal blog with Docker. You want that sweet, sweet HTTPS padlock for secure connections, and Let's Encrypt is the obvious choice for free SSL certs. Awesome! You set up your reverse proxy (maybe Traefik, because it's slick!), point it to your app, and tell it to get a certificate... only to hit a wall. Why? Meet the home networker's nemesis: ISPs blocking incoming port 80. The Standard Way (and the Wall) Let's Encrypt's default validation method, HTTP-01, is simple: their servers try to access a special file on your server over standard HTTP (port 80) to prove you control the domain. Let's Encrypt -> Your Public IP:80 -> Does challenge file exist? -> OK! Cert Issued! But if your ISP blocks incoming connections …  ( 5 min )
    Very Basic - Redux
    Learning Redux is a real pain in the @#$#$^&. Good thing the team I was on at the time I learned it highly valued taking the time to learn, because it took me a good 30 out of 40 hours of a work week to figure out what the eff was going on. Once I finally did learn it however, I realized that the majority of what slowed me down in the learning process was that I couldn’t find a great explanation of exactly what Redux was doing. All I could find were tutorials on how to use it, and not really very much info on how it worked. I’m going to try to solve that issue with this post. I’m also going to assume that you know how to use React, and that you know what Redux is and why you want to learn it.

    5 Developer Productivity Hacks That Saved Our QA Testing Time by 70%
    The Testing Time Crisis When our team started building a new fintech application last year, we hit an unexpected bottleneck: testing time. With multiple user roles, complex verification flows, and strict security requirements, our QA cycles grew from days to weeks. This wasn't just frustrating—it was directly impacting our release velocity and team morale. After several painful sprints, we implemented five changes to our testing approach that dramatically reduced our testing time without compromising quality. I'm sharing these because they've been game-changers for us, and they might help your team too. One of our biggest time sinks was manually creating test users with different permission levels. We solved this with an automated provisioning system. // Example of our user provisioning …  ( 5 min )
    Building Efficient Test Data for Development Environments: Solving Verification Workflow Challenges
    Introduction As developers, we all face the hidden challenge that rarely gets discussed in coding tutorials: generating and managing test user data at scale. This becomes particularly problematic when building applications requiring email verification, multi-user testing, or complex authentication flows. After struggling with this issue on several projects, I've discovered some effective approaches worth sharing. If you've ever found yourself creating multiple Gmail accounts just to test a simple registration flow, you know the pain I'm talking about.

    Singly Linked Lists - DSA Notes 📝
    🎯 Learning Goals What are the characteristics of Singly Linked Lists? What are its time complexities? ListNode? Has a value and a next pointer next is a reference to another ListNode Order in memory may not be contiguous (unlike arrays which are) Simple while loop with a current pointer can be used: cur = ListNode1 while cur: cur = cur.next ⌚ Time complexity is O(n) , where n is the number of nodes in the linked list Now if the Linked List is circular (i.e. last node points back to first) traversing like this would cause an infinite loop. It would be helpful if we’re keeping track of the head and the tail of the linked list using pointers Advantage over array is that inserting is always O(1) even if we insert in middle. Let’s say we wanna add at the end or tail : tail.next = NewListNode tail = NewListNode # or this line 'tail = tail.next', both are correct ⌚ Time complexity is O(1) Removing any node is constant time ASSUMING we have a pointer to the previous node. Let’s say we wanna remove the second node: head.next = head.next.next # Just set the next pointer of head to the one after the deleted node Can be assumed that garbage collection will take place for the deleted node ⌚ Time complexity is O(1) For both of these operations, the caveat is if we don’t have a reference to the node at the desired position (head or tail), the time will still be O(n) Operation Big-O Reading/ Access O(n) Traversal/ Search O(n) Insertion O(1)* Deletion O(1)* *Assumes you have a reference to the node at the position (if not it is O(n) ) 206.

    FT report suggests advance knowledge of Melania Trump memecoin launch
    A group of crypto traders reportedly purchased millions of dollars worth of Melania Trump’s memecoins minutes before she announced the launch on social media. According to a May 6 Financial Times report, the crypto traders earned roughly $100 million from buying $2.6 million worth of MELANIA tokens before the public launch on Jan. 19. Shortly after Trump announced the memecoin launch on social media, the price surged from roughly $2.00 to $12.95 — a 550% increase. The traders reportedly sold their holdings within 12 hours. “In total, the 24 accounts bought up 16.7mn of the 200mn total $MELANIA tokens scheduled for sale during the launch period,” the Financial Times reported. “[...] the run of sales that started pre-launch continued. About $900,000 worth of tokens bought by an additional 22…
    Bitcoin could rally regardless of what the Federal Reserve FOMC decides this week: Here’s why
    Key Takeaways: The Fed may pause rates but inject liquidity. Crypto could rally as a recession hedge. The weak US dollar and gold rally signal a shift to scarce assets. The US Federal Reserve Open Market Committee (FOMC) interest rate decision on May 7 will be a defining moment for risk-on assets, including cryptocurrencies. While the consensus points to no change in interest rates, Bitcoin (BTC) and altcoins could see gains if the US Treasury is compelled to inject liquidity to stave off an economic recession. A more accommodative monetary policy could stimulate activity, but the Federal Reserve (Fed) is also contending with a weakening US dollar. Some analysts argue that a US interest rate cut may fail to stimulate growth as recession risks persist, potentially creating an ideal envir…

    Bitcoin bulls rush into long positions ahead of May 7 Fed FOMC interest rate decision
    Key Takeaways: Data shows Bitcoin bulls opening margin long positions from $94,400. A $189 million increase in Bitcoin futures open interest and a 15% increase in trading volume show sustained buying interest. BTC momentum tends to slow before FOMC meetings and then turns volatile afterward. The same could happen following this week’s Federal Reserve statements. Bitcoin (BTC) bulls are holding strong around the $94,500 level as the market awaits the Federal Open Market Committee (FOMC) meeting on May 7. Bitcoin analyst Axel Adler Jr. noted BTC’s price strength and pointed out a bullish cluster of long positions forming around $94,400 in the futures market. A similar cluster was observed at the end of April, which pushed BTC prices to $97,500. Bitcoin futures position dominance data. So…

    Bitcoin price rallied 1,550% the last time the ‘BTC risk-off’ metric fell this low
    Key Takeaways: The Bitcoin Risk-Off signal dropped to 23.7, its lowest since March 2019, indicating low correction risk and a high likelihood of a bullish trend developing. Despite the recent decline in network activity, bullish macro indicators like the Macro Chain Index (MCI) suggest Bitcoin could soon rally above $100,000. On May 5, the Bitcoin Risk-Off signal, an indicator that uses onchain and exchange data to assess correction risk, dropped to its lowest level (23.7) for the first time since March 27, 2019, when Bitcoin (BTC) traded at $4,000. The signal is currently in the blue zone, which historically suggests low correction risk and a high probability of a bullish trend. When the oscillator rises above 60 or turns red, it implies a high risk of bearish movement.  Bitcoin Risk-O…

    North Korean spy slips up, reveals ties in fake job interview
    For months, Cointelegraph took part in an investigation centered around a suspected North Korean operative that uncovered a cluster of threat actors attempting to score freelancing gigs in the cryptocurrency industry. The investigation was led by Heiner Garcia, a cyber threat intelligence expert at Telefónica and a blockchain security researcher. Garcia uncovered how North Korean operatives secured freelance work online even without using a VPN. Garcia’s analysis linked the applicant to a network of GitHub accounts and fake Japanese identities believed to be associated with North Korean operations.

    Frictionless flows are Ethereum's path to economic dominance
    Opinion by: Barna Kiss, CEO of Malda An idea recently floated by some prominent thinkers in the Ethereum space to reclaim value for the mainnet is the taxing of its Layer-2s. The future of Ethereum does not depend on policy but on enabling frictionless capital movement between the L2s in question. Tariffing rollups may appear a neat way to reclaim value for the mainnet. In practice, it would fragment the ecosystem, drain liquidity, push users toward centralized platforms, and avoid decentralized finance altogether. In a permissionless system, capital flows to where it is treated best, and Ethereum's rollups mistreat it. Liquidity fragmentation is Ethereum's real threat In traditional finance, the link between fluidity and growth is well established. Lower barriers to capital inflows lead …
    What bankers, CPAs and CFOs need to know about blockchain
    Why finance veterans are still skeptical about blockchain Blockchain has been part of the finance conversation for over a decade now. Yet many professionals remain cautious.  Many seasoned professionals in finance, wealth management and economics often question blockchain’s relevance, asking, How exactly is blockchain supposed to fit into what we already do? This question reflects a few key ongoing skepticisms about blockchain within finance. Uncertainty about practical applications Blockchain offers some big promises: faster settlements, stronger security and better transparency. But actually applying those promises across banking, accounting and operations is still complicated. A 2021 APQC survey identified the main hurdles: a lack of industry-w…
    Dem lawmakers object to hearing, citing 'Trump’s crypto corruption'
    Representative Maxine Waters, ranking member of the House Financial Services Committee (HFSC), led Democratic lawmakers out of a joint hearing on digital assets in response to what she called “the corruption of the President of the United States” concerning cryptocurrencies. In a May 6 joint hearing of the HFSC and House Committee on Agriculture, Rep. Waters remained standing while addressing Republican leadership, saying she intended to block proceedings due to Donald Trump’s corruption, “ownership of crypto,” and oversight of government agencies. Digital asset subcommittee chair Bryan Steil, seemingly taking advantage of a loophole in committee rules, said Republican lawmakers would continue with the event as a “roundtable” rather than a hearing. HFSC Chair French Hill urged lawmakers at the hearing to create a “lasting framework” on digital assets, but did not directly address any of Rep. Waters’ and Democrats’ concerns about Trump’s involvement with the crypto industry. He claimed Waters was making the hearing a partisan issue and shutting down discussion on a digital asset regulatory framework. This is a developing story, and further information will be added as it becomes available.

    US stablecoin bill loses democrats amid Trump corruption concerns
    Democratic lawmakers in Washington are backing off support for crypto legislation amid heightened concerns over corruption, including the conduct of the Trump family’s World Liberty Financial (WLFI). In March, the GENIUS Act, which would regulate stablecoins in the US, passed a critical committee reading with the support of several pro-crypto Democrats. Democratic Senators Ruben Gallego, Mark Warner, Lisa Blunt Rochester, Andy Kim and Angela Alsobrooks voted with Republicans, opposite lead Democrat and prominent crypto critic Senator Elizabeth Warren. The bill passed the committee only after a number of changes were made, including stricter requirements for stablecoin issuers and provisions for Anti-Money Laundering, countering terrorism financing and risk management procedures.  Now, it s…
    Why is XRP price down today?
    Key takeaways: Ripple's end-to-quarterly market report fuels uncertainty, impacting XRP price negatively. Low open interest in XRP futures signals weak trader confidence. XRP price technicals weaken with resistance at $2.27 and declining RSI. XRP (XRP) fell on May 6, down 3% in the last 24 hours to trade at $2.09, due to numerous factors.

    Bitcoin price forms two BTC futures gaps after Coinbase premium flips negative
    Key takeaways: Bitcoin’s Coinbase premium index turned negative for the first time in 15 days, indicating defensive short-term sentiment among US investors. Bitcoin CME futures gaps between support at $92,000-$92,500 and resistance at $96,400-$97,400 suggest a period of range-bound trading. Bitcoin’s Coinbase premium index, which measures the gap between BTC price at Coinbase Pro and Binance exchange, turned negative after a 15-day positive stint, signaling potential bearish sentiment among US investors. This drop coincides with Bitcoin (BTC) slipping below $94,000, and the premium’s decline suggests reduced buying pressure on Coinbase, which is viewed as a proxy for both institutional and retail demand.

    Blockchains ready for institutions, lawyers hesitate: DoubleZero CEO
    While blockchain infrastructure may be ready for institutional use, many legal teams at large firms remain cautious about full integration with the technology.  At the Token2049 event in Dubai, DoubleZero Labs founder and former Solana head of strategy Austin Federa told Cointelegraph that today's high-performance blockchains like Solana are technically capable of supporting large-scale institutional usage. However, lawyers still need to catch up.  “Most blockchains nowadays, especially things like Solana, are fast enough for institutions to use them,” Federa said. “It’s really more about the institutions and the institution’s lawyers getting comfortable with crypto.” Federa added that institutional lawyers and compliance teams are still addressing regulatory concerns. The executive said t…
    Research DAO claims paralyzed rats recover after spinal cord fix
    Decentralized autonomous organization (DAO) HydraDAO claims that its researchers were able to use a novel technique to repair severed spines in rats. In a May 5 X post, decentralized science (DeSci) project HydraDAO said that one of its research projects resulted in “rats who had their spines fully transected” being able to walk again. More notably, recovery from surgery reportedly only took five days. Source: HydraDAO The post featured a video of partially shaved (presumably due to surgery) rats walking in what appeared to be a laboratory setting. The effort in question is the Dowell spinal fusogens project led by Michael Lebenstein-Gumovski, which raised 380,700 USDC (USDC) from donors. The dedicated HydraDAO page reads: “The Dowell team submitted a project proposal to HydraDAO. After ca…

    Crypto spending will grow, but fiat isn’t going anywhere: Mercuryo CEO
    Petr Kozyakov, CEO of crypto payments platform Mercuryo, told Cointelegraph that the future of finance may not be a winner-takes-all scenario but a blend of digital assets and fiat, each used where it makes the most sense.  In a Cointelegraph interview, Kozyakov said that while crypto payments are seeing an increase in adoption and demand, the asset class won’t be fully replacing fiat money anytime soon. He said the two asset classes will coexist, with people choosing the more convenient payment option in different situations.  “We don’t think crypto will replace fiat,” Kozyakov told Cointelegraph. “They will coexist, and people will turn to crypto when it’s the easier, more practical option, whether that’s for payroll, yield or money transfers.” Mercuryo Petr Kozyakov at the Token2049 eve…
    IRS appoints Trish Turner to head crypto division amid resignations
    Veteran US Internal Revenue Service (IRS) official Trish Turner was appointed to lead the agency’s digital assets division following the departure of two key crypto-focused executives. Turner, who has spent over 20 years at the IRS and most recently served as a senior adviser within the Digital Assets Office, will now head the unit, according to a report from Bloomberg Tax citing a person familiar with the situation. Her promotion marks a significant leadership transition at a time when US crypto tax enforcement is facing both internal and external pressures. On May 5, Sulolit “Raj” Mukherjee and Seth Wilks, two private-sector experts brought in to lead the IRS’s crypto unit, exited after roughly a year in their roles.

And if you can see that everyday value, then that is a promising project,” Mahasneh told Cointelegraph. He said hype can drive project growth in the Web3 space, but providing everyday value should be the priority.  OKX…
    Bitcoin vs. digital fiat is freedom vs. serfdom
    Opinion by: Simon Cain, contributor at Bitcoin Policy UK Most jurisdictions globally are researching, developing or implementing retail central bank digital currencies (CBDCs). If you see these as harmless move-with-the-times digital updates of old-fashioned paper money, look again. CBDCs potentially mean financial serfdom via a monetary panopticon where the authorities closely control every transaction.  If you think this sounds paranoid, just consider the words of Augustin Carstens, head of the Bank for International Settlements — the central bank for the world’s central banks. Lamenting the authorities’ current inability to control cash transactions, he says that with a CBDC, a “central bank will have absolute control on the rules and regulations that will determine use... also we will …
    US Senate crypto bills stall amid Trump ties and ethics concerns
    Efforts to pass crypto legislation in the US Senate face mounting resistance amid growing ethical concerns around US President Donald Trump’s ties to crypto. In a May 5 letter to the US Office of Government Ethics, Senators Elizabeth Warren and Jeff Merkley said that Trump and his family stand to personally profit from an investment involving UAE state-backed firm MGX, crypto exchange Binance and World Liberty Financial (WLFI). The senators called for an urgent probe, warning the deal may violate the US Constitution’s Emoluments Clause and federal bribery statutes. At the center of the controversy is WLFI’s USD1 stablecoin, reportedly chosen for a $2 billion investment MGX plans to make into Binance. The senators said the transaction amounts to a potential backdoor for foreign influence an…
    Bitcoin Core to unilaterally remove controversial OP-Return limit
    Bitcoin Core developers have decided to remove a limit on transaction data in the next network upgrade, enabling more data to be included in a more efficient way.  “Bitcoin Core’s next release will, by default, relay and mine transactions whose OP_RETURN outputs exceed 80 bytes and allow any number of these outputs,” read the announcement on GitHub by Bitcoin developer Greg Sanders on May 5.  The long-standing limit was originally a “gentle signal that block space should be used sparingly for non-payment proof of publication data,” has outlived its utility, he added.  The proposal (PR 32359) was created by Bitcoin pioneer Peter Todd at the request of Chaincode Labs.  OP_RETURN is a special type of Bitcoin (BTC) transaction output that allows storing small amounts of data on the blockchain,…
    Celsius’ Mashinsky lashes out at ‘death-in-prison sentence’
    Alex Mashinsky, the founder and former CEO of bankrupt crypto lending platform Celsius, has blasted the government's 20-year “venom-laced” sentence request, declaring it a “death-in-prison sentence.” The US Department of Justice requested Mashinsky receive at least 20 years behind bars in the May 8 sentencing for his role in misleading Celsius users and profiting from the price manipulation of Celsius (CEL), which would make the 59-year-old 79 if he serves the whole sentence. Lawyers acting for Mashinsky argued in a May 5 reply memorandum filed in a New York district court that he should receive no more than 366 days, because the DOJ hasn't taken into account his status as a nonviolent first-time offender with a previously unblemished 30-year history in business.   “The government's venom-…

    Suspect in $190M Nomad hack to be extradited to the US: Report
    A Russian-Israeli citizen allegedly involved in the $190 million Nomad bridge hack will soon be extradited to the US after he was reportedly arrested at an Israeli airport while boarding a flight to Russia.  Alexander Gurevich will be investigated for his alleged involvement in several “computer crimes,” including laundering millions of dollars and transferring stolen property allegedly connected to the Nomad Bridge hack in 2022, The Jerusalem Post reported on May 5. Gurevich returned to Israel from an overseas trip on April 19 but was ordered to appear before the Jerusalem District Court for an extradition hearing soon after, according to the report.  On April 29, Gurevich changed his name in Israel’s Population Registry to “Alexander Block” and received a passport under that name at Isra…
    Florida takes strategic Bitcoin reserve bills off the table
    Two Florida crypto bills have been removed from the legislative process in the latest blow to American state-level strategic Bitcoin reserve ambitions.  Florida’s House Bill 487 and Senate Bill 550 have been “indefinitely postponed and withdrawn from consideration” on May 3, according to the Florida Senate.  Florida’s legislative session adjourned on May 2 without the passage of these two bills, which would have advanced legislation to establish a crypto reserve for the state. The Senate and House agreed to extend the session until June 6 to address budget plans.  Lawmakers passed about 230 bills during the session, dealing with things like prohibiting putting fluoride in the water, protecting state parks, and a school smartphone ban, but diversifying state treasury portfolios was not amon…
    Tron says DAO X hack cost victims $45K, Curve Finance also hit
    A hacker who took over the Tron DAO X account is estimated to have made around $45,000 in improperly solicited funds, according to a spokesperson from Tron.  Speaking to Cointelegraph, the Tron public relations team confirmed that on May 2, the Tron DAO account posted a contract address and sent direct messages to solicit payments in exchange for promotional advertising on the Tron account. “Our security team quickly identified the intrusion and cut off access to the hacker, but we ask the community to continue to be vigilant. We will never ask anyone for payments like this via DM or otherwise,” they said.  The team said that based on the illicit contract address the hacker posted, the amount improperly solicited appeared to be around $45,000.  Asked whether the same hacker could be respon…
    Fresh $1B in Tether mints on Tron, closing gap again with Ethereum
    The Tron network has drawn closer to regaining the lead from Ethereum in Tether circulation after another big mint by the US stablecoin issuer. On May 5, Tether minted another $1 billion Tether (USDT) on the Tron network, according to Arkham Intelligence. This brings the total USDT on Tron to $71.4 billion, according to the Tether Transparency report.  In comparison, there is currently $72.8 billion USDT circulating on the Ethereum network, so just $1.4 billion more USDT on Tron will see it become the leading network for the world’s largest stablecoin issuer, as it has been previously over the last two years.  Tron was ahead of Ethereum for USDT circulation between July 2022 and November 2024, but a large $18 billion mint on Ethereum pushed the network ahead again, according to CryptoQuant…
    New crypto bill draft seen to curb big crypto firm influence
    The new “Digital Asset Market Structure Discussion Draft” introduced by House Republicans on May 5 could work to reduce the dominance of large crypto firms and promote more participation in the broader market, according to an executive from Paradigm.  The discussion draft, led by the House agricultural and financial services committee chairs Glenn Thompson and French Hill, is an “incremental, albeit meaningful, rewrite” of the Financial Innovation and Technology for the 21st Century Act (FIT21), Paradigm’s vice president of regulatory affairs Justin Slaughter said in a May 5 X post.

    Samourai Wallet says feds hid advice that crypto mixer was in the clear
    Samourai Wallet’s lawyers allege federal prosecutors suppressed advice that the firm didn’t need a license before they charged executives at the crypto mixing service months later.  In a May 5 letter to a Manhattan federal court, lawyers for Samourai co-founders Keonne Rodriguez and William Hill said prosecutors disclosed that the US Treasury Department’s Financial Crimes Enforcement Network (FinCEN) representatives told them six months before they charged the pair “that under FinCEN’s guidance, the Samourai Wallet app would not qualify as a ‘Money Services Business’ requiring a FinCEN license.” “Shockingly, six months later, the same prosecutors criminally charged Keonne Rodriguez and William Hill with operating just such a business without a FinCEN license,” the lawyers added.

    How to Specify a Different Linker in GCC and Clang?
    Introduction When compiling programs in C or C++ using cc or c++, you may find yourself needing to use a different linker than the default one. For instance, your version of GCC or Clang might link against /usr/bin/ld. In many scenarios, developers want to test their applications with alternative linkers, like /usr/local/bin/ld, for various reasons, including performance evaluation or compatibility testing. In this article, we’ll explore how to specify a different linker without running separate compilation steps. Why the Default Linker Matters The linker plays a crucial role in the compilation process, as it's responsible for combining different object files into a single executable.

    Landing from Clouds: Why On-Premise Will Eventually Win
    “The computer industry is the only industry that is more fashion-driven than women’s fashion.” Larry Ellison In our era, the cloud is the haute couture of infrastructure. Everyone wants it. Everyone says you need it. And few ask whether it actually fits. This post is for those who remember that not every problem needs 12 layers of abstraction. It's for careful builders who believe that owning your tools is better than renting your soul. And here are 12 reasons why on-premise will outlast the hype. The cloud sells convenience, but charges premium rent, forever. When you buy servers, you own an asset. When you rent a VM, you feed a meter.

    How Harrison G Herdzik Manages Tech Clients Efficiently as a Student Founder
    Hey Devs, I’m Harrison G Herdzik — a full-time tech student at Western Connecticut State University and founder of Harrison’s Tech Solutions, a small business offering practical IT support for local clients. Balancing academics, client requests, and business admin might sound chaotic, but I’ve developed a lightweight but effective workflow that keeps me sane and productive. Here’s how I do it — and how you can adapt it to your own side-hustle or service-based business. 🧰 My Tech Stack for Client Management CRM & Task Tracking: Notion Scheduling & Booking: Calendly Remote Support: AnyDesk Invoicing: Wave Communication: Gmail + Google Meet Documentation: Google Docs + Loom for quick video walkthroughs Each tool solves a specific problem. The goal isn’t complexity — it’s clarity and control. **💬 How I Communicate With Clients *Here’s my approach: Keep emails concise but informative Use screen recordings (Loom) when words fall short Set clear expectations and timelines from the start Document every service — even one-off calls That’s something I learned early on: people appreciate clarity, not cleverness. **⏱️ Time Management as a Student & Founder ⏰** Morning:** Classwork, assignments 💻 Afternoon: Scheduled client calls or remote work 📑 Evening: Admin tasks, follow-ups, learning new tech tools By blocking time and batching tasks, I reduce context switching. And if a client emergency comes up? I leave a 1-hour buffer each day just in case. 🚀 Advice from Harrison Herdzik to Aspiring Student Founders Your first client might be a family friend — that’s okay. Document your work. It builds trust and repeat business. Say no to bad fits. Focus on clients you can genuinely help. Keep learning. The tech world changes fast — be ready.

    How to Fix Modal Animation Issues with Button Elements
    Understanding the Issue with Modal Animations If you've ever tried to implement a modal that slides in from the bottom after being triggered by a button, you might have encountered an unexpected behavior when using a element inside your modal dialog. This is a common issue that developers face, especially when working with CSS animations. In this article, we will explore why this issue occurs and how you can fix it effectively. Why Does This Happen? The problem often arises from the way CSS handles layout changes during animations. When the modal is opened, if a button element is included, it may trigger a reflow in the browser’s layout engine. This reflow can result in the appearance of a scrollbar, which disrupts the fluidity of your animation. The pointer-events property combin…  ( 4 min )

    Evite requisições desnecessárias com debounce em JavaScript
    Você já digitou algo em um campo de busca e, a cada letra digitada, uma nova requisição era feita para a API? Isso é ineficiente. A solução? debounce() debounce? É uma técnica usada para adiar a execução de uma função até que um tempo específico tenha passado sem novas chamadas. É muito usado em: buscas dinâmicas (auto-complete) eventos de rolagem (scroll) eventos de resize Imagine um campo de busca que chama a API a cada tecla: function search(term) { fetch(`https://api.exemplo.com/search?q=${term}`) .then(res => res.json()) .then(console.log); } input.addEventListener("input", (e) => { search(e.target.value); }); Isso gera chamadas demais. Agora, com debounce: function debounce(fn, delay) { let timer; return (...args) => { clearTimeout(timer); timer = setTimeout(() => fn(...args), delay); }; } const debouncedSearch = debounce(search, 500); input.addEventListener("input", (e) => { debouncedSearch(e.target.value); }); Agora só é chamada a API depois que o usuário parar de digitar por 500ms. No React, pode usar com useCallback ou bibliotecas como lodash.debounce: import debounce from 'lodash.debounce'; const debounced = useCallback( debounce((value) => { // chamada de API aqui }, 300), [] ); Conta aqui nos comentários como implementou 👇 Ou salva esse post pra usar depois! 🔖  ( 3 min )
    How to Remove Cast in Hibernate Queries for DB2 z/OS?
    Introduction If you're working with Hibernate and querying a DB2 z/OS database, you might have faced a common issue where the generated SQL queries include unnecessary cast statements, especially after upgrading to Hibernate 6. This can cause errors as certain DB2 versions don't support those casts. In this article, we will explore why this issue occurs and provide solutions to remove the cast statements for compatibility with DB2 z/OS. Understanding the Problem In Hibernate, SQL query generation can change between versions due to changes in how Hibernate handles type conversions. After upgrading to Hibernate 6, many users report encountering errors like: Could not convert 'java.lang.Character' to 'java.lang.String' using 'org.hibernate.type.descriptor.java.StringJavaType' to wrap This pa…  ( 5 min )
    Understanding Laravel's Arr::dot() Method
    When working with deeply nested arrays in Laravel, especially when handling configuration files, API responses, or multidimensional data structures, managing or accessing values quickly becomes complex. Laravel’s Arr::dot() method offers a clean, efficient way to flatten these arrays using “dot” notation, making them much easier to work with. In this article, we’ll explore what Arr::dot() does, how it works, and when you might want to use it. The Arr::dot() method in Laravel flattens a multidimensional array into a single-level array using dot notation for keys. This transformation allows you to access deeply nested values with a simple key string. Arr::dot(array $array, string $prepend = '') $prepend: (Optional) A string to prefix each key in the final array. This method is part of Laravel’s Illuminate\Support\Arr helper class. Let’s take a look at a typical example: Input Array $data = [ Applying Arr::dot() $flattened = Arr::dot($data); print_r($flattened); [ 'user.name' => 'John', 1. Configuration Files 2. Localization 3. Form Handling Bonus: Reversing the Flattening $nested = Arr::undot($flattened); Arr::dot() is a small but powerful utility in Laravel that simplifies the handling of complex arrays. Whether you're building APIs, working with config files, or cleaning up nested data structures, this helper can be a time-saver and make your code cleaner and more readable. Next time you're faced with a deeply nested array, consider reaching for Arr::dot() — you’ll appreciate the simplicity it brings.  ( 4 min )

    🐳 Understanding Docker's Default Bridge Network (With Diagram)
    If you've ever spun up a Docker container and wondered how does this thing talk to the internet?, you’re not alone.

    Permissions API to Manage User Consent
    Comprehensive Exploration of the Permissions API for Managing User Consent Historical and Technical Context The emergence of web technologies has ushered in a new era of interactivity and real-time applications. However, with such capabilities comes the critical responsibility of user privacy and consent. The Permissions API was standardized as part of the broader movement to provide enhanced privacy practices on the web, enabling developers to manage user permissions more systematically. The Permissions API was introduced to address the concerns posed by previous blind consent models, which often left users unaware of the degree of access they were granting. Traditionally, permissions like location access, notifications, and camera/microphone use were either all-or-nothing, l…  ( 6 min )

    How to Create a PHP Registration Form as a Single Page Application?
    Creating a multi-page registration form in PHP can be cumbersome, especially when the pages require reloading for navigation. If you're experiencing slow load times with your current method—where each page requires a new HTTP request—you might want to consider converting your form into a Single Page Application (SPA). This approach enhances user experience by loading the HTML just once and using JavaScript to handle navigation smoothly. Understanding the Issue When using multiple pages for form registration, each time a user clicks the 'Next' button, a new HTTP request is sent to the server, which loads a new page. This results in a complete refresh, including reloading CSS, JavaScript, and images, leading to inefficient use of resources and slow loading speeds. A Single Page Application a…  ( 4 min )
    New browser in town
    I like testing new browsers, these days I use Firefox more than chrome, but I always have Opera and Edge. Today I saw this video https://youtu.be/9YM7pDMLvr4?si=R7X_wdJVqqRB3TNB Andreas explaining what is Ladybird browser and why they are developing it. So I went to https://github.com/LadybirdBrowser/ladybird checked out the code and build it on WSL2 Windows 11, took around 3 hours to compile and finally it worked UI looks similar to Firefox and feels like #Netscape in 1999, and it is developed actively, I hope we have a new and free browser because feels like Firefox is not that free anymore and Google has been too strong on browser market, it would be nice to have a real non-profit browser here. Maybe government/countries should support this kind of organizations otherwise browsers or OSes becoming like citizen monitoring tools and used for profit and manipulation, After we say internet is a human right that human should have the option of non monitored communication use in their home. And in the YouTube video Andreas talks about SerenityOS which looks very similar to Windows 95, good old days. It is a good idea to have unix like OS as desktop.

    🚀 Do zero ao primeiro SaaS: 3 erros que me ensinaram mais do que qualquer acerto
    Em janeiro, decidi tirar minha ideia de SaaS do papel. O objetivo? Aprender na prática como levar um produto do conceito à loja. Confesso que foi uma onda de desafios (e ainda está sendo!). Como era meu primeiro projeto, cometi vários equívocos. Eu queria compartilhar alguns abaixo ⤵️ — e como eles estão me ajudando a evoluir: 🔥 Planejamento impulsivo   Fui direto da ideia para a solução, sem mapear etapas ou prazos. Resultado? Retrabalho e ansiedade. Hoje, priorizo ferramentas de gerenciamento e cronogramas flexíveis para manter o foco sem engessar a criatividade. 🔍 Validação superficial   Criei o SaaS para resolver meu problema, mas não validei se era uma dor real do mercado. Consequência? Perdi tempo competindo com soluções já consolidadas. Aprendi que entrevistas com potenciais usuários são tão importantes quanto o código. 💸 Precificação "no feeling"   Foquei em funcionalidades incríveis, mas não pensei em como monetizá-las de forma atraente. Lição? Agora estudo modelos de precificação antes de sair desenvolvendo novas features, usando cases de sucesso como referência. ✨ O saldo positivo?   Esses tropeços me deram algo valioso: clareza. Hoje entendo melhor que errar faz parte do processo — desde que cada erro vire um degrau para iterar. E você? Já passou por situações assim em seus projetos?  ( 3 min )

    GAEB4Linux – Open Source GAEB Viewer/Editor for Linux (Java/XML)
    Hey dev.to! GAEB4Linux, which aims to bring native support for GAEB files (a German construction industry standard) to Linux. GAEB is a widely used XML-based format for exchanging construction data in Germany. It’s essential for things like bills of quantities, tender submissions, costing, and invoicing. There are plenty of GAEB software tools available, but almost all of them are Windows-only or commercial. Linux users in the construction industry currently have no solid open-source solution to handle GAEB files. The goal is to create an open-source GAEB file viewer/editor for Linux (written in Java for cross-platform compatibility). The initial version will support: Viewing GAEB XML files (e.g., .X83, .X84), Entering bid data and prices for tenders, Later stages could include additional features like full AVA (tendering and invoicing) functionality. 🌱 Current Status: Right now, I’m in the early planning phase – no code has been written yet. I’m designing the system, figuring out the core features, and planning how to integrate the GAEB XML structure. Developers familiar with Java, XML, and GUI design (Swing/JavaFX, etc.), Anyone with experience in the construction industry or knowledge of GAEB/AVA workflows, Designers or UX/UI specialists who can help build an intuitive interface, Feedback from anyone who has worked with GAEB or similar standards. I’m planning to host the project on GitLab, and I’ll set up a chat (Discord/Matrix) for discussions and collaboration. Would love to hear your thoughts or suggestions, and I’m open to any tips from anyone who has experience with GAEB file handling. Thanks for reading! —Klaus  ( 3 min )

    Starvation in Javascript: When your program remains Hungry
    If you've spent time working with JavaScript's asynchronous model, you know that its single-threaded nature is both a blessing and a curse. On one hand, you don't have to worry about complex locking mechanisms. On the other, you might stumble into weird issues where your code just... never runs. One such issue is starvation. In the context of JavaScript, starvation refers to a situation where a task is perpetually delayed because the event loop is constantly busy with other tasks—usually of higher priority or those scheduled more frequently. Since JavaScript executes code in a single-threaded environment using an event loop, starvation can occur when: Long-running synchronous code blocks the event loop.

    “It Looked Right…” Famous Last Words Without Tests
    TL;DR: LLMs are great, but they’re not your safety net. Please, for the love of all things holy, test your code. We’re in the golden age of vibe coding. LLMs scaffold our code, fix our syntax, and fill in the blanks. We’re thinking more about architecture and less about syntax—and that’s great. But in all this abstraction, we sometimes skip something essential: testing. AI doesn’t run your code. It doesn't know if that method exists, if that call will throw an error, or if that edge case breaks everything. It’s bluffing with confidence. You can’t vibe your way through correctness. You need tests to know your code behaves the way you think it does. 🛡 Confidence to refactor without fear 🧠 Clarity around what your code is supposed to do 🔄 Continuity when you revisit the code 6 months later 🤝 Collaboration with teammates who now understand the logic A mentor once told me: “Start at the center—your happy case. Then go left, right, and fall off the line.” Say your function expects a positive integer. Start with 42. Then try: 0, -1, Infinity, -Infinity A string ("hello"), a float (3.14), or null Now take it further: What if the parameters are undefined? What if the database call fails? What if the API returns malformed or missing data? What if a field you depend on is null? The real world is messy. Your tests should be ready for that. As we stop writing every line ourselves, we need to start questioning every line more. AI will get you to “working”—but testing gets you to “works when it matters.” AI bluffs. Don’t let it bluff you into a broken release.  ( 3 min )

    Grumphp en proyectos Ddev
    Grumphp es un orquestador que permite configurar el uso de herramientas de código estático para PHP. Hasta hace relativamente poco tiempo he usado W4D como entorno de desarrollo en mis proyectos, pero hace un año me tocó probar Ddev para un proyecto y desde entonces me enamoré de todo lo que aporta este software. Ahora toca migrar proyectos que tengo con W4D a Ddev y una de las cosas que toca migrar es Grumphp. Para instalar Grumphp yo uso el paquete de Carcheky que está preparado para funcionar con Drupal y luego lo personalizo. Ejecuto el siguiente código para instalar el paquete: composer config extra.grumphp --json '{"config-default-path": "vendor/carcheky/drupal-grumphp/configs/grumphp.yml"}' ; composer require --dev carcheky/drupal-grumphp -W Una vez instalado copio el archivo grumphp.yml que se encuentra en vendor/carcheky/drupal-grumphp/configs/grumphp.yml a la misma altura del archivo composer.json En el archvio composer.json busco la configuración de grumphp y actualizo config-default-path de la siguiente manera: "grumphp": { "config-default-path": "grumphp.yml" } En el archivo grumphp.yml que hemos copiado a la raíz del proyecto buscamos la configuraciónde git_hook_variable y lo actualizamos de la siguiente manera: git_hook_variables: EXEC_GRUMPHP_COMMAND: ddev exec php Por último en la consola ejecuto el siguiente comando para actualizar la configuración del hook pre-commit ddev exec grumphp git:init De esta forma actualizaremos el hook pre-commit de nuestro proyecto (los hooks pre-commit están en la ruta '/.git/hooks/pre-commit`y el archivo queda así: `bash DIFF=$(git -c diff.mnemonicprefix=false -c diff.noprefix=false --no-pager diff -r -p -m -M --full-index --no-color --staged | cat) export GRUMPHP_GIT_WORKING_DIR="$(git rev-parse --show-toplevel)" (cd "./" && printf "%s\n" "${DIFF}" | ddev exec php 'vendor/bin/grumphp' 'git:pre-commit' '--skip-success-output') `  ( 3 min )

    React Compiler RC: What it means for React devs
    Written by David Omotayo✏️ The React compiler is one of the biggest updates to the React framework in years. Last year, the React team released a beta version. Around that time, I wrote an article called “Exploring React's Compiler: A Detailed Introduction”. It unpacked the core idea behind the compiler and showed how it could improve React development by automatically handling performance issues behind the scenes. When the beta dropped, the React team encouraged developers to try it out, give feedback, and contribute. And many did. A standout example is Sanity Studio. They used the compiler internally and shipped libraries like react-rx and @sanity/ui that are optimized for it. Thanks to contributions like these, the React team officially released the first Release Candidate (RC) on Apr…  ( 10 min )

    AWS Storage Explained: Choosing Between File, Block, and Object Storage Like a Pro
    Ever felt like you're drowning in data? You're not alone. In today's digital world, applications generate and consume information at an unprecedented rate. Choosing how and where to store that data in the cloud is one of the most fundamental – and often confusing – decisions architects and developers face. Pick the wrong type, and you could end up with slow performance, skyrocketing costs, or an architecture that just doesn't scale. You look at the AWS console, and the options seem endless: S3, EBS, EFS, FSx... what's the difference, and when should you use each? It feels a bit like walking into a massive hardware store looking for a screw – you know you need something to hold things together, but the sheer variety of options is overwhelming.

    A Look into CTags: The Secret Map of Your Codebase
    Have you ever opened a massive codebase and wished you could jump straight to the definition of a function, class, or variable without scrolling endlessly? That's exactly what CTags is for. In this post, we’ll break down what CTags is, how to use it, and—most importantly—how to read a tags file CTags (short for "C Tags") is a tool that scans your code and generates an index of where functions, variables, classes, and other identifiers are defined. This index is saved in a file called tags. Suppose you have this simple math_utils.py file: def add(a, b): return a + b def subtract(a, b): return a - b Run this in your terminal: ctags -R . You’ll now see a file called tags in your directory. tags File? Here’s what it might look like: add math_utils.py /^def add(a, b):$/;" f s…  ( 4 min )
    How to Detect Offline/Online Status in ReactJS
    Have you ever wanted to notify users when they lose internet connectivity in your React app? Today we build AppShell component together that monitors the browser's online/offline status and shows a user friendly message when the user goes offline. Realtime apps (like chat, stock tickers, etc.) depend on live connectivity. Offline-friendly experiences build trust and reliability. It's surprisingly easy to implement. Lets Wrap the entire app (or any major layout component) with AppShell: navigator.onLine: Detects the initial connection status. window.addEventListener("online"/"offline"): Reacts to changes in network status. useEffect: Registers and cleans up event listeners when the component mounts/unmounts. Let me know how you're handling offline states in your apps :)  ( 3 min )

    How to Dynamically Configure REST API URLs in Angular
    Introduction If you're new to Angular and transitioning from server-side development, one common challenge is configuring your application to dynamically connect to your Spring REST API. While hardcoding URLs might be the simplest immediate solution, it often causes issues when deploying to different environments. In this article, we will discuss various approaches to effectively manage API URLs in your Angular application, ensuring a smooth deployment process. Understanding API URL Management When building applications that interconnect with REST APIs, it's crucial to manage API URLs efficiently. Typically, during development, you'd use one server endpoint (localhost), while production might require a completely different URL. Hardcoding API endpoints makes it challenging to adapt to thes…  ( 5 min )
    Go #008 – Closures: Escape Analysis in Action
    Closures in Go are powerful but come with hidden memory implications. By capturing variables from their surrounding scope, they force the compiler to decide: Should these variables live on the stack or heap? Let’s dissect real-world examples to see escape analysis in action. The Code package main func counter() func() int { count := 0 // Escapes to heap (captured by closure) return func() int { count++ return count } } func main() { // Closure captures heap-allocated variable c := counter() println(c()) // 1 println(c()) // 2 // Loop closure pitfall var funcs []func() for i := 0; i < 3; i++ { funcs = append(funcs, func() { println(i) // i escapes to heap…  ( 4 min )

    How NoLogin Was Born: From a Computer Lab Frustration to a Sharing Revolution
    It all started back in 3rd sem — during one of my computer lab session. My friend had just executed his code — and it worked perfectly. So what happened? He had to log into Gmail on the lab PC That’s when I had this thought: Googled and found already existing ones like dontpad So, for the next couple of weeks, all of us started using dontpad — mostly just copy-pasting code, sharing it as soon as someone got it working. Whoever cracked the problem first would dump the code there, and the rest of us would just grab it and run. Then one day, I was sitting in class and noticed how our teacher logged into her Gmail just to download a PPT and present it to the class. That moment stuck in my mind — but I got busy with other things and didn’t think much of it. A few days later, one of our teachers…  ( 4 min )

    Bring third-party incidents into Better Stack
    Incidents in cloud and SaaS tools block users just as hard as faults in your own code. The fix comes faster when the same on-call queue covers both. IsDown now plugs straight into Better Stack through a native API connection. Every outage that IsDown detects shows up as an incident in Better Stack, follows your existing escalation rules, and clears automatically once the vendor recovers. Vendor downtime seldom triggers your own uptime probes—the traffic never reaches you. IsDown closes that gap by checking hundreds of official status pages round the clock. When those signals land inside Better Stack, responders work from a single incident list. No tab-hopping, no split workflows. A shared queue also tightens communication. Stakeholders follow one channel, post-mortems cover both internal a…  ( 4 min )
    When is it necessary to split a dataset for Analysis? Is it before, or after we clean the data? That is the question.
    ** ** What is data? Data, in its simplest form, is raw, unprocessed facts and figures. It can be numbers, text, images, or any other form of information that can be stored and processed by computers. Data becomes meaningful information when it is analyzed, interpreted, and placed in context. Therefore, Data is the basic unit of information before it's been organized, analyzed, or interpreted. What is information? In data science, splitting your dataset effectively is an important initial step towards building a robust model. Generally, you'll want to allocate a larger portion of your data for training, very often around 70%-80%, with the remaining 20%-30% for testing. This allows the model to learn from a substantial amount of data while still retaining enough unique data points to test …  ( 8 min )

    TS1436: Decorators must precede the name and all keywords of property declarations
    TS1436: Decorators must precede the name and all keywords of property declarations TypeScript is a robust, statically-typed programming language designed as a superset of JavaScript. Simply put, it enhances JavaScript by adding type definitions (a way to explicitly define the type of values) and other powerful features like interfaces, enums, and decorators. This makes it easier to work with larger codebases and prevent runtime errors by catching issues during the compile time. For those just starting out, think of TypeScript as a tool that adds structure and safety to JavaScript without changing its core nature. If you're building complex applications or working in a collaborative team, TypeScript helps make your code predictable, maintainable, and scalable. Type definitions form the c…  ( 6 min )

    Part 2 of Pattern Matching in Switch - Java
    This is the part 2 of the blog covering switch expressions in Java. If you haven't read part 1 yet, please give it a read here as it would cover some of the basic understanding of the switch expression and pattern matching in switch. Java compiler doesn't force exhaustiveness in switch statements, whereas switch expression are expected to be exhaustive. What really is exhaustiveness? Exhaustiveness ensures that all possible cases are handled in a switch expression, either explicitly or with a default case. For example, When you use an enum type, switch must cover different values of the enum. This is not limited to enums, its applicable to all the types switch supports. Look at the below versions of code, former one with switch statement and the later with switch expressions. This snippet…  ( 6 min )

You don’t need many AI agents, one for each task. An agent can call as many tools as it needs. AI independently decides what tool it should use and when. Write a precise prompt and correctly declare what tools AI can access and when it should be used. You should care what you save in the session state. AI agents could save the output to the session state, and different agents in your AI pipeline could access it. While developing, you should navigate to t…  ( 5 min )
    API Testing Essentials: What Every QA Engineer Should Know
    If your organization relies on software to deliver value, APIs are already at the epicenter of your digital infrastructure. They connect your systems, enabling you to scale through integration and automation and deliver superior customer experiences. But what’s often overlooked is that APIs are only as reliable as your ability to test them effectively. Unlike traditional UI testing, which focuses on the frontend layer, testing them gives you visibility into the actual mechanics of your app—the business logic, the rules that drive decisions, and the integrations that connect your systems. If you don’t validate that layer thoroughly, you leave core functionality exposed, increasing security risk.

    How to Fix Executable Path Issues in .NET Core 3 Single File Builds
    Introduction Upgrading an application to .NET Core 3 often brings a variety of enhancements, one of which is the option to publish a single-file executable. While this has its advantages, many developers encounter path-related issues during the build process, particularly related to the PublishSingleFile flag. This article addresses a common problem where the executable path defaults to a temporary directory, disrupting access to vital resources. Understanding the Issue When you set the PublishSingleFile flag, the .NET runtime modifies how executable paths are resolved. Instead of locating the executable file in its original directory, it often redirects to a location like /var/tmp/.net/. This behavior occurs due to the way the runtime handles unpacking the single-file executable at runtim…  ( 5 min )

Checked Exceptions (compile-time exceptions) Must be declared or handled (using try-catch or throws) Examples: IOException, SQLException, ClassNotFoundException Unchecked Exceptions (runtime exceptions) Not checked at compile time Examples: NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException Errors Serious problems that applications should not try to catch Examples: OutOfMemoryError, StackOverflowError Exception Handling Keywords try: Block of code to monitor for exceptions catch: Block that handles the exception finally: Block that always executes (for cleanup) throw: Used to explicitly throw an exception throws: Declares exceptions that might be thrown by a method try { // Code that might throw an exception int result = 10 / 0; // This will throw ArithmeticException } catch (ArithmeticException e) { System.out.println("Cannot divide by zero!"); } catch (Exception e) { System.out.println("General exception caught"); } finally { System.out.println("This will always execute"); } You can create your own exception classes by extending Exception (checked) or RuntimeException (unchecked): class MyCustomException extends Exception { public MyCustomException(String message) { super(message); } } Catch specific exceptions rather than general Exception Don't ignore caught exceptions (empty catch blocks) Use finally blocks for resource cleanup Document exceptions with @throws in JavaDoc Consider whether to handle, propagate, or convert exceptions Would you like more details on any specific aspect of Java exceptions?  ( 3 min )

    Python Cheat-Sheet
    Intro Happy revenge of the fifth! This week, I've been working with Python as I learn more about Machine Learning. I thought it'd be a good idea to put together a cheat-sheet that summarizes some of the things I've learned so far. This is a work in progress, and I will be adding more to it as I learn more. Comments, variable assignment, adding, conditionals and printing. rarecandy_count = 0 print(rarecandy_count) # Found 4 more Rare Candy while exploring Route 119 rarecandy_count = rarecandy_count + 4 if rarecandy_count > 0: print("Sweet!

    The Christmas holiday period always brings some opportunity to sneak in some time for hobby projects. Either its because the rest of the family is still sleeping in during the morning or to just sit with the laptop next to the kids while they look a Christmas movie. During recent years end period there was a lot of excitement about the deepseek model, released open source, so i decided to give it a try to run local. First setting up the environment. From my ethical hacker lab I was already used of using oracle box (with Kali), so I continued in that space. https://dev.to/pavanbelagatti/run-deepseek-r1-locally-for-free-in-just-3-minutes-1e82 Setting up went fast, although there where as usual some extra libraries to upgrade.

    Import/Export: Default vs Named (And Why Some Use Braces)
    If you've worked with React or JavaScript modules, you might have noticed that sometimes you write imports with curly braces ({}) and sometimes without them. Ever wondered why? Let’s break it down. A default export allows a module to export a single value. It’s useful when your file exports just one main thing — like a component. // components/Footer.jsx export default function Footer() { return ...; } import Footer from './components/Footer'; 🚫 No curly braces needed for default exports. A named export allows you to export multiple values from a file. You must import them using curly braces. // components/Contact.tsx export function Contact() { ... } export function AnotherHelper() { ... } import { Contact } from './components/Contact'; ✅ Curly braces required for named exports. You can combine both in one file: export default function App() { ... } export function Helper() { ... } Then import like: import App, { Helper } from './App'; Hope this clears up the mystery behind those curly braces!

    MVC, MVP, and MVVM: Simple in Appearance, Powerful in Practice
    Leapcell: The Best of Serverless Web Hosting MVC stands for Model View Controller, which is an abbreviation for model-view-controller. It is a widely applied software design paradigm. Its core idea is to organize the code by separating the business logic, data, and interface display, and centralize the business logic in one component. In this way, when improving and customizing the interface and user interaction, there is no need to rewrite the business logic. MVC has uniquely developed to map the traditional input, processing, and output functions into a logical graphical user interface structure.

    Vacuous Truth in JS
    Just the other day I was testing a permissions function when I came across something very interesting about Array.prototype.every. So, let me give you a little back story. The function I was testing is a a very simple one that check whether a user has permissions required to access given module or action. This function happened to use the JS array method called every How every works is that it loops through the array and checks whether all items satisfy a provided condition. If it encounters any item that doesn’t it break the loop and returns false, however if all items satisfy the conditions then true is returned. However, there is a peculiar behavior to this method in that if an empty array is used then true is still returned. This is where the concept of vacuous truth comes in // typesc…  ( 4 min )

    What is Database Server?
    database server is a server which uses a database application that provides database services to other computer programs or to computers, as defined by the client–server model.[citation needed][1][2] Database management systems (DBMSs) frequently provide database-server functionality, and some database management systems (such as MySQL) rely exclusively on the client–server model for database access (while others, like SQLite, are meant for use as an embedded database). Users access a database server either through a "front end" running on the user's computer – which displays requested data – or through the "back end", which runs on the server and handles tasks such as data analysis and storage. In a master–slave model, database master servers are central and primary locations of data while database slave servers are synchronized backups of the master acting as proxies. Most database applications respond to a query language. Each database understands its query language and converts each submitted query to server-readable form and executes it to retrieve results. Examples of proprietary database applications include Oracle, IBM Db2, Informix, and Microsoft SQL Server. Examples of free software database applications include PostgreSQL; and under the GNU General Public Licence include Ingres and MySQL. Every server uses its own query logic and structure. The SQL (Structured Query Language) query language is more or less the same on all relational database applications. For clarification, a database server is simply a server that maintains services related to clients via database applications. DB-Engines lists over 300 DBMSs in its ranking.  ( 3 min )
    AWS Config vs Kubernetes Native Policy Engines: Who Governs What?
    In modern cloud-native environments, compliance, governance, and standardization are critical to ensuring security, operational efficiency, and regulatory adherence. As organizations adopt containerized infrastructure, enforcing consistent policies across platforms like Amazon EKS (Kubernetes-based) and ECS (serverless containers) becomes increasingly complex. At first glance, AWS Config and Kubernetes-native policy engines like OPA Gatekeeper and Kyverno may appear to serve the same function — enforcing rules and ensuring compliance in containerized workloads. But in reality, they operate at different layers, solve distinct problems, and target different scopes of governance. AWS Config is designed for cloud-wide compliance across AWS resources, whereas Kubernetes-native engines are focus…  ( 7 min )

    What is Data Mart?
    A data mart is a structure/access pattern specific to data warehouse environments. The data mart is a subset of the data warehouse that focuses on a specific business line, department, subject area, or team.[1] Whereas data warehouses have an enterprise-wide depth, the information in data marts pertains to a single department. In some deployments, each department or business unit is considered the owner of its data mart, including all the hardware, software, and data.[2] This enables each department to isolate the use, manipulation, and development of their data. In other deployments where conformed dimensions are used, this business unit ownership will not hold true for shared dimensions like customer, product, etc. Warehouses and data marts are built because the information in the datab…  ( 4 min )

    Is Big Data Dying?
    In recent years, the notion that “big data is dying” seems to be gaining traction. Some say the big data craze has faded, while others lament the shrinking job opportunities, the increasing complexity of platforms, and the growing intricacy of business demands. But does this really mean big data is dying? I don’t think so. In my view, what’s truly dying is not big data itself, but rather the outdated “dragon-slaying techniques” that no longer have any “dragons” to slay. The “dragon” has evolved, while our weapons remain stuck in the past. Technology needs to evolve, architectures need to be restructured, and capabilities need to be upgraded. To understand the current state and trends of big data, we must first examine how it has evolved step by step. The development of big data can be divi…  ( 8 min )

    Goodbye Spaghetti State: Query Objects Make React Filters Clean & Easy
    When you're building a dynamic frontend—like a game store, product listing, or job board—your UI needs to handle a lot of state: What page are we on? What filters are selected? Are we sorting by newest, most relevant, or trending? What platform, genre, or tags are selected? Managing all of that with separate useState hooks or deeply nested props can quickly become a nightmare. Enter the Query Object Pattern. A Query Object is a single JavaScript object that encapsulates all your query parameters—filter values, sort order, pagination, etc. const [query, setQuery] = useState({ genreId: null, platformId: null, sortOrder: 'relevance', searchText: '', page: 1, }); Instead of spreading your state across multiple hooks: const [genreId, setGenreId] = useState(null); const [platformId, s…  ( 4 min )

This is the false sense of progress that many learners experience in their programming journey. At the beginning of learning programming, it’s common to feel like we are advancing rapidly. Solving coding problems and watching tutorials can give us the impression that we're progressing. But when it comes to solving more complex problems or applying what we've learned to re…  ( 5 min )
    Virtual Machines vs. Containers: Unmasking Limitations and Celebrating Heroes
    Limitations of Virtual Machines and Servers? 1. Startup & Shutdown Times: VMs generally take longer to start up and shut down compared to containers, which can impact the speed of deployment and scaling. This delay can be a bottleneck in environments requiring rapid provisioning and de-provisioning of resources. 2. Dynamic Resource Allocation is Complex: VMs rely on hypervisors(such as VMware ESXi, Microsoft Hyper-V) to manage and allocate resources like CPU, memory and storage. This adds complexity because the hypervisor needs to handle various resource demands and ensure fare distribution. (Earlier we would need to Shutdown the VM for changing the allocated resources but now this can be done on a running instance as well but it still needs input/human intervention and its complex) Aut…  ( 4 min )

    📦 At Most Once, At Least Once, Exactly Once: What Do These Really Mean?
    message queues or event streaming platforms play a critical role in enabling this communication. But here's the key question: How reliably is a message delivered from sender to receiver? Let’s break down the three core delivery semantics you’ll encounter in real-world systems 👇 At-Most Once 🔹 Messages are delivered zero or one time No retries, so if something fails — the message is lost no guarantee of delivery 💡 Use case: Monitoring metrics, logs, or telemetry where occasional loss is acceptable. At-Least Once 🔹 Messages are never lost may be delivered multiple times deduplicate on the consumer side 💡 Use case: Order processing, notifications, analytics — where duplicates can be filtered or ignored. Exactly Once 🔹 Each message is delivered only once, no duplicates, no loss very hard to implement complexity, latency, and often performance trade-offs 💡 Use case: Financial transactions, trading systems, accounting — where idempotency is not supported and every operation must be precise. Choosing the right delivery guarantee isn’t just about tech — it’s about your use case and business priorities. a single duplicate message could cost thousands. 📌 Message Queue vs Event Streaming Platform? 🔹 Message Queues (like RabbitMQ, SQS): Focus on reliability and order for point-to-point communication. 🔹 Event Streaming Platforms (like Kafka, Pulsar): Optimized for broadcasting, storing, and replaying high-throughput event logs. Ideal for event-driven systems and real-time analytics. What’s your go-to strategy for delivery semantics in distributed systems? Let’s discuss in the comments 💬  ( 4 min )
    Hey Frontend Devs, Feeling Slowed Down by Your CMS?
    Let’s be honest. You've spent hours wrangling with bloated WordPress themes or waiting on backend fixes just to launch a simple page. Sound familiar? It’s not you. It’s the traditional CMS model. Let’s talk about why headless CMS is the quiet hero that’s helping frontend developers like you build faster and smarter. What Is a Headless CMS (And Why Should You Care)? In dev-speak: it’s a CMS without a front-end layer. In real talk: it gives you content via API and lets you build the frontend however you want. So instead of battling clunky plugins and rigid templates, you’re free to code with your favorite stack — React, Next.js, Vue, whatever. 1. Speed Boost with Modern Dev Tools Headless CMS platforms are made to play well with modern JavaScript. You can: Pull content via REST or GraphQL Use static site generators like Next.js for blazing performance Integrate easily with CI/CD workflows Translation? You ship faster — and with less backend drama. 2. Frontend Freedom = Faster Iteration No more begging backend devs to make a template change. With headless, you’re in full control of the UI/UX. Want to test a new layout or animation? Go for it. Your content comes clean and structured — so you can design and iterate freely. ## 3. Better Dev-Content Team Workflow They update copy. You build features. No blockers. 4. Scale Without Slowing Down Need to serve content across web, mobile, and IoT? No problem. You can scale globally, without rebuilding everything from scratch.

    My Go-To Toolkit: Top 10 Shadcn/ui Components I Rely On for Modern Web Development
    The landscape of frontend development is constantly evolving, especially when it comes to UI components. For years, we've juggled comprehensive libraries like Material UI, Ant Design, or Chakra UI. They offer a wealth of pre-built components, but often come with trade-offs: heavy bundle sizes, complex style overrides, and a feeling of being locked into their specific ecosystem and design opinions. Then came Shadcn/ui, and for many developers like myself, it fundamentally changed the game. Shadcn/ui isn't a component library in the traditional sense. It's better described as a curated collection of beautifully designed, highly reusable UI primitives and components built using Radix UI for behaviour and accessibility, and Tailwind CSS for styling.

    I built gitNull: A minimalist GitFlow CLI tool to save time and stay focused
    Hello Dev.to community! 👋 As a developer, I often found myself repeating the same Git commands over and over again during my workflow... So I built a small CLI tool called gitNull to make that easier! gitNull? A lightweight GitFlow helper written in Node.js. It automates common git actions like: gitNull start-feature gitNull finish-feature gitNull push – adds, commits and pushes in one command With a retro CLI look and some colorful feedback thanks to chalk and figlet. I love clean workflows, and I always wished Git had something a bit more guided. I didn’t want a full GUI — just a faster terminal flow. This is my first attempt at building a CLI tool, and I'm sharing it to get feedback and ideas from the community. Check it out on GitHub: https://github.com/faithreborn/gitnull Whether you're a CLI junkie, a GitFlow user, or someone who just hates typing long commands — I’d really appreciate if you give it a try and tell me what you think. ❤️ Any feedback, issues or PRs are welcome!

    Why You Should Boycott VS Code
    Microsoft's Visual Studio Code, commonly just called VS Code, is a great piece of software. This is in no small part due to all extensions on the extensive marketplace providing extreme flexibility. It has proven it to be adaptable to most, if not all, software development projects. My editor of choice, neovim, provides no such benefits out of the box, requiring me to configure everything, install language plugins, code completion, myself. Vim and neovim are by far more powerful editors, but lacking the ease-of-use of VSCode, and easy discoverability of new features; I don't recommend beginners to use these. Configuration is done through code, not a nice UI allowing you to browse a marketplace and take popularity into consideration when choosing between different plugins for the same task…  ( 8 min )

    Building a Prediction Market on Chromia | Step 3 — Creating Events and Writing Your First Operation
    Today we’ll create our first entity, learn how to create events, write a simple query to fetch all events, and of course, test everything to make sure it actually works. Let’s start with the basics. We’ll define our first entity, which is essentially just a SQL table. In it, we need to specify the field names and their types. The first entity will be called event. It will store all the core info about each event: the account of the user who created it, the question text, creation time, expiration time, a flag that shows whether the event is closed, and the result. I want to directly link each event to its creator’s account. For that, we’ll use the type ft4 account, which represents a user in the FT4 system.

    Understanding gRPC: The Power of Single Long-Lived Connection
    When using gRPC, one of its biggest advantages over traditional REST is the use of a single long-lived connection over HTTP/2. What does that mean? Unlike REST where every request opens a new connection, gRPC establishes one persistent connection between the client and the server. Through this connection, multiple messages can be exchanged — in both directions — without reopening it each time. Think of it like this: Imagine going to a restaurant. With REST, you’d have to enter and exit the restaurant every time you wanted to order something new. But with gRPC, you sit down once, and continue to place multiple orders and have conversations — all through that single session. Benefits of gRPC’s Long-Lived Connection: ✅ Reduced latency ✅ Real-time communication ✅ Efficient use of resources ✅ Bidirectional streaming supported Use Cases: Perfect for real-time apps like online games, chat systems, IoT devices, and microservice communications — where speed and efficiency matter most.  ( 3 min )
    Recurrent Neural Networks (RNNs): A Comprehensive Guide
    Introduction The concept of sequence modeling is fundamental to understanding RNNs. Many real-world problems involve sequences, where the order of elements carries significant meaning. For example, in language, the meaning of a sentence depends heavily on the order of the words. Similarly, in video analysis, the sequence of frames determines the action being performed. RNNs excel at capturing these dependencies, making them a powerful tool for a wide range of applications. The application of RNNs is prevalent in the field of deep learning. The history of RNNs is marked by continuous evolution. Early RNN architectures faced challenges like the vanishing gradient problem, which hindered their ability to learn long-range dependencies. However, innovations like Long Short-Term Memory (LSTM) …  ( 7 min )

    Synesthetic Data Interfaces: Turning Code into Color, Sound, and Touch
    What If You Could Feel Data? This amazing idea is becoming real through something called synesthetic data interfaces. That’s a big name, but it simply means using your senses—like hearing, sight, or touch—to understand data.

This chain of digital certificates connects users to websites through verification steps. For more detailed information you can refer article certificate chain of trust At the top of the chain is the Root Certificate. This is issued by a Root Certificate Authority (CA). These root certificates are pre-installed and trusted by operating systems and browsers. Since they are self-signed, they serve as the anchor of trust for the entire chain.

    Expectation 'Hired to Love' 🖤Reality DNS Rescue 😫
    After a frustrating day dealing with a broken pipeline at work, all I wanted was to relax with a good story on Wattpad. 😌 I opened the app on my phone, and something strange happened. The home page loaded fine, but when I tried to open any story, I got stuck on an endless loading screen. At first, I thought it was temporary maintenance. But after a week of the same issue, I knew something else was wrong. I did some digging on Reddit and found a pattern: Only Jio users in India were having this problem 🇮🇳 The Wattpad home screen would load, but stories wouldn't People using other networks like Airtel had no issues I tested this by connecting to my Airtel hotspot instead of my Jio data, and suddenly Wattpad worked perfectly!

    RBAC vs. LBAC: Which Scales for Multi-Tenant Dashboards?
    The Multi-Tenant Dashboard Dilemma This article explores RBAC and LBAC in Grafana, highlighting real-world best practices, pitfalls to avoid, and actionable insights to scale efficiently.

    Level Up Your Integration Tests in .NET: Record, Replay, Relax
    Sick of flaky integration tests? You run your tests once — they pass. Run them again — they fail. Maybe the third-party API timed out. Or the response changed. Or your internet blinked. Integration tests should give you confidence, not stress. That’s where deterministic integration testing comes in. Imagine recording your API interactions once and replaying them forever — offline, fast, and predictable. No network. No surprises. That’s exactly what Vcr.HttpRecorder does. It’s inspired by the original Ruby VCR gem, revived for .NET and brought back to life with new features and bug fixes in my fork. In traditional integration tests, you call real services — maybe a payment gateway, an external API, or even another microservice. But real services are unpredictable: They might be slow or d…  ( 5 min )
    Quark’s Outlines: Python Delimiters
    Overview, Historical Timeline, Problems & Solutions When you write Python code, you use symbols to separate, group, or define parts of the program. These symbols are called delimiters. A delimiter does not perform an action like an operator. Instead, it marks structure and boundaries. In writing, you use punctuation to make ideas clear. A comma breaks up items. A period ends a sentence. In Python, delimiters help the interpreter make sense of what comes next. Python uses delimiters to shape the structure of your code. (1 + 2) * 3 ['a', 'b', 'c'] {"key": "value"} x = 7 def f(): pass You use delimiters to build lists, assign values, pass arguments, and group code. Python requires these markers so it can read your program correctly. When you write a list, call a function, or create a diction…  ( 6 min )

    I Rebuilt My Personal Website with Eleventy — Here’s Why I Wanted It Simple
    jienweng.com Hi all. I recently rebuilt my personal site using 11ty, and I wanted to share a bit about why I chose simplicity over flashy design. Like many developers, I started with a more complex stack — Astro, React, lots of moving parts. It looked cool, but it started to feel like I was building for the tools instead of myself. So I started over with 11ty. It’s fast, flexible, and just lets me focus on content. Tbh I hate npm, and with 11ty i like that there's no bundlers, no frameworks. Just clean HTML, Markdown, and a bit of templating. The site is still a work in progress, but I like how it feels now — more personal, less performative. It’s a place for my notes, thoughts, and projects. Nothing fancy. Just mine. Would love any feedback or thoughts — especially from others who’ve simplified their stacks or gone the “digital garden” route. Thanks for reading!  ( 3 min )

"Find out if you're a passionate coder in less than 5 minutes with 10 easy-to-answer questions." The best coders I've met at past jobs weren't what we'd call passionate. By passionate, I mean making open source contributions, speaking at conferences, and writing posts. They were busy enough making money. The other day, Miguel, one of my email subscribers, shared a similar experience. Here's an excerpt of his email: Personally, I've become discouraged in my programming career and no longer aspire to work at one of the most important tech companies. I just want to pay my bills and meet my family's needs.…  ( 4 min )

    How to Exclude Rows While Using SQL Outer Join?
    Introduction When working with SQL, especially with outer joins, it's crucial to understand how to filter your results effectively. In your case, you're looking to perform a right outer join between two tables and then conditionally include or exclude rows based on the status from one of these tables. This article will break down how to efficiently filter results using outer joins in SQL while ensuring you get data according to specific conditions. Understanding the Outer Join Behavior Outer joins, particularly the right outer join you mentioned, are designed to include all the entries from the right table (in this case, table2), along with matching rows from the left table (table1). If there are no matches, SQL will return NULL for columns from table1. This behavior poses a challenge when…  ( 4 min )

    How to Travel
    Pack your bags up the day before. Make sure to get the basics, underwear, socks, toothbrush, medications, pjs, travel documents, license, passport, – don't get deported, little gifts, etc... 'etc...'? This etcetera is the other stuff you forget and will inevitably have to purchase at your destination. Yes, I account for this because sometimes it doesn't matter how much time ahead I pack there is usually something I missed packing and have to either bother a relative to let me borrow it. I don't love forgetting stuff but at this point I rather forget than having to change my ways, like packing weeks before like my mother does. Smart lady, never forgets anything. I'm more like my dad in these type of things. 'Men'. I'm not sure if it's a fair thing to asume, 'all men are bad at packing' but I tell you, there is a pattern. My male cousin, doesn't travel, I wonder if he would also suck at packing. I think having a comfortable amount of money makes you care less because you can just purchase what you forget at the place where you go to maybe, – saying this in the most possibly humble way. For example, I forgot to pack belts, now I have to go to a store and buy something I already had for free at home.  ( 3 min )
    Messaging Made Simple with RabbitMQ-Stream
    A lightweight RabbitMQ framework for Node.js, built to eliminate boilerplate and let you focus on business logic. Let’s say you’re building an app with several moving parts—maybe one service processes user signups, another sends welcome emails, and another tracks analytics. Normally, these services would need to talk to each other directly and immediately—which makes things tightly connected and harder to scale. Messaging and event-driven architecture solve this by letting each part send and receive information independently. It works like this: When something important happens (like a new user signing up), that part of the app sends a message—think of it like dropping a letter in a mailbox. RabbitMQ. Here’s a simple example: A user signs up → The app sends a user.created message → The > e…  ( 6 min )
    How to Create a Fibonacci Sequence in JavaScript?

    🌀 The Ritual Scheduler
    “Summon a daily contribution. Maintain the illusion. Worship the green.” You ever stare at your GitHub contribution graph like it's a Tamagotchi you forgot to feed? Yeah, me too. So I built something unholy: A Bash-based automation daemon that ensures your GitHub profile always looks... alive. It commits. It pushes. It even wakes your computer from the dead to do it. ⏰ Schedules fake-but-believable commits at randomized human hours 🔁 Retries if GitHub rejects your offering 💾 Logs your ritual attempts and successes 🌴 Vacation mode, so your ritual pauses when you need rest (or alibis) 🔥 Self-healing if a ritual was missed (triggered by guilt and grep) 👁️ macOS popup warnings like: > “⚠️ No ritual detected today. The square is empty. You are exposed.” 🧙 Choose your commit incantations like: feat: added function nobody asked for fix: removed existential crisis from variable name 📜 Add custom altar messages 🔓 Unlock rare achievements like: "100 Days of Devotion" "The Sacred Streak" ✅ Daily ritual cron + safety check daemon 🪞 GitHub visibility flip (goes public, commits, hides again) 🧙‍♀️ Bash installer with prompt-based setup 🏕️ Vacation flag toggle for burnout mercy 🧾 .command launcher for double-click ritualism 🎨 Coming Soon: SVG badges GitHub profile theme pack Guilt Daemon™ (shames you in Slack when your squares go dark) Yes.

    Still lost in Voronoi Diagrams
    This is going to be a quick Devlog, because I just want to get back to this issue I'm having and figure out a solution for it. I've gone back to the drawing board, trying to figure out how to effectively unwrap the donut-shaped Voronoi diagram I have for my river tiles. I think this is the third week I've been working on the same problem now, so I'm getting a little frustrated because 3 weeks is a lot of time that could have been spent working on some other part of the game. I just feel like when I do solve this, one - I won't have to think about it again, and two - the visual pay-off will have been worth it. I also feel like I've invested too much time to not get some kind of pay-off for this feature. The biggest issue that I'm having is that when I have the shapes aligned as they leave one of the corner tiles and enter the straight tile, by the time they flow along the straight path in time to reach the bottom, they're not quite aligned. Now I think the problem I'm having is that I've got a slight overlap on the tiles, the row beneath covers the row above by a couple of pixels - enough to make the borders around the tiles match up. This looks fine in practice, but I need to compensate for that when aligning the shapes, and I feel like this is throwing a spanner in the works. So, I'm redoing my hex grid, and I'm using this article as a reference... https://www.redblobgames.com/grids/hexagons/ I'm going to try and math my way through this tonight. Wish me luck! Cheers, Dan.  ( 3 min )
    Import a large CSV more than 1G into a database quickly
    This article will introduce how to quickly import csv or txt files larger than 1g into the database. Here, we prepared a CSV file with 10 million rows x 30 columns x 4GB. At first, I tried to import it with Navicat. The first problem I encountered was that the encoding format was unknown, which led to many attempts to find the correct encoding. The second problem is that Navicat reads and writes one by one. Although this does not take up memory, the speed is very slow. The third problem is that halfway through the import, an error was reported because the field length was not enough! ! ! I had to reset the field length and import from 0 again. . . What's worse is that after setting one field, another error was reported. . . Now, we use the DiLu Converter Import tool to solve these problems one by one. Encoding: It can be automatically identified by default (for files with unknown encoding). If the encoding format of the file is known, you can select or enter its encoding format to speed up the parsing speed. Chunk Size: You can set the number of rows to import at a time according to the available memory of your computer. My computer has a total of 16G memory, about 9G is available, and 500,000 is set in a batch. Here, you must set the size according to the available memory. If the setting is too large, the memory may overflow, and if the setting is too small, it will not speed up. And The just click start You can see that it takes about 20 seconds to import a batch of 500,000 rows, and the memory usage is less than 1G Finally, it took about 5 minutes to import this csv file of 10 million rows x 30 columns x 4GB, and the maximum memory usage was about 1G. Because the tool imports files in batches according to batch size, no matter it is 1 file or hundreds or thousands of files, no matter a single file is 1G or 100G, as long as the batch size is set reasonably, it can be imported quickly, stably and without consuming memory.  ( 4 min )
    How to Create a Generic Structure with a Default Type in Rust?
    Creating generic structures in Rust can initially seem challenging, especially when it comes to default types. In this article, we will explore how to create a generic structure with a default type, allowing users to omit the generic parameter when defining instances. We’ll investigate why the Rust compiler requires explicit type annotations in certain situations and provide a step-by-step solution to this common problem. Why Does Rust Require Explicit Type Annotation? Rust is a statically typed language, which means types are known at compile time. When you define a generic structure, the compiler often needs to understand what specific type to use for the generics. In your code example, you're trying to instantiate C without specifying its type, which results in the following error: erro…  ( 4 min )
    🔁 1128. Number of Equivalent Domino Pairs – Explained with Code in C++, JavaScript, and Python
    If you’ve ever played with dominoes, you know that the order of the numbers doesn’t matter—[1,2] is the same as [2,1]. That's the central idea behind this popular LeetCode problem: 💡 Given a list of dominoes, return how many pairs of dominoes are equivalent. Two dominoes [a, b] and [c, d] are equivalent if: (a == c and b == d) or (a == d and b == c) Let's dive into the most optimal way to solve this! Instead of comparing every pair (which would take O(n²) time), we can: Normalize each domino: [a, b] becomes [min(a, b), max(a, b)] Use a hash map to count how many times each normalized domino appears. Every time we see a duplicate, we count how many previous identical dominoes we've seen. Add that count to the result (because every new domino can pair with all previous identical ones).

    # OpenSearch : 🚀 How to Improve Index and Shard Performance in OpenSearch
    OpenSearch, a powerful distributed search and analytics engine, offers high scalability and near real-time search capabilities. However, as data volume and query complexity grow, performance bottlenecks often emerge—particularly around indices and shards. This guide breaks down actionable strategies to optimize indexing, querying, and shard management for improved performance and cluster health. Index: A logical namespace that maps to one or more physical shards. Shard: A basic unit of storage and search in OpenSearch. Each shard is a Lucene index. Performance is tightly tied to how indices and shards are structured, distributed, and queried. Too many shards create overhead; too few limit concurrency. Aim for ideal shard sizes between 10–50 GB. Avoid the default 5 shards unless justified. …  ( 4 min )

No obstante, ante este conjunto de beneficios, la adopción de esta arquitectura en cualquier proyecto puede resultar riesgosa si no se aborda con una comprensión profunda de las mejores prácticas. Una arquitectura de microservicios mal diseñada puede fácilmente igualar, o incluso superar en complejidad y dificultades, a un sistema monolítico tradicional. Im…  ( 4 min )

    New York district gets interim US Attorney as ex-SafeMoon CEO trial kicks off
    Acting US Attorney for the Eastern District of New York (EDNY) John Durham has departed as President Donald Trump’s pick takes control of the office. In a May 5 notice, the US Attorney’s Office for EDNY said Joseph Nocella will serve as interim US Attorney for the region for 120 days or until a Senate-confirmed nominee assumes the role. Nocella’s appointment came as jury selection began in the criminal trial of Braden John Karony, the former CEO of crypto firm SafeMoon. It’s unclear how the advancement of Nocella, appointed by US President Donald Trump this month, could affect prosecutors’ case against Karony, who faces charges of securities fraud conspiracy, wire fraud conspiracy, and money laundering conspiracy. Nocella said he intended to help prosecute “narcotics-traffickers, gang memb…
    OpenAI to stay nonprofit, scrap proposed overhaul
    ChatGPT-maker OpenAI has abandoned plans to become a for-profit company and reaffirmed commitment to its nonprofit status.  In a May 5 blog post, OpenAI confirmed plans to convert its for-profit business unit into a so-called Public Benefit Corporation (PBC), which would remain under the nonprofit’s control. PBCs are for-profit companies that are legally obligated to prioritize a social mission alongside the interests of shareholders. The plans mark a reversal for OpenAI, which had previously floated a for-profit conversion involving spinning out the nonprofit entity. “OpenAI was founded as a nonprofit, and is today overseen and controlled by that nonprofit. Going forward, it will continue to be overseen and controlled by that nonprofit,” the ChatGPT-maker said.  This can be done without…
    Good actors were 'unfairly targeted' by SEC — OpenSea's CEO
    The Securities and Exchange Commission’s (SEC) enforcement approach on crypto firms has left a lasting “regulatory overhang” within the industry, according to Devin Finzer, co-founder and CEO of OpenSea.  Speaking to Cointelegraph, Finzer said that during Biden's administration the agency unfairly targeted good actors in the crypto space, including OpenSea. “There's all sorts of digital assets, you know, you shouldn't treat them all the same. That's obvious. But I think the approach that the prior SEC was taking was kind of this, you know, very, very generic.” The SEC issued a Wells notice — a formal notification that is often a precursor to enforcement action — to OpenSea in 2024, alleging that the NFT marketplace was operating as an exchange for unregistered securities. At the time, Finz…
    Trump’s crypto dealings face scrutiny as House Republicans unveil digital asset bill
    US President Donald Trump’s crypto businesses are drawing increased scrutiny on Capitol Hill and beginning to influence the progress of US digital asset legislation. As Republican lawmakers in the US House of Representatives unveiled their draft of a digital asset market structure bill on May 5, Democrats prepared for a united response to Donald Trump’s deepening connections with the industry. Speaking to Cointelegraph on May 5, a Democratic staffer with knowledge of the matter said that House Financial Services Committee Ranking Member Maxine Waters planned to lead some members of her party out of a Republican-led hearing discussing digital assets. The May 6 hearing, entitled “American Innovation and the Future of Digital Assets” and led by Committee Chair French Hill, could address draft…
    Bitcoin sell-off to $93.5K is a brief hiccup — Data still supports new BTC highs in 2025
    Key takeaways: Bitcoin price slips, but BTC dominance is on the rise. Sizable purchases by Strategy and the spot BTC ETFs highlight institutional investors’ appetite for Bitcoin. Bitcoin’s (BTC) price has dropped by 4.3% in the last three days after nearly reaching $97,900 on May 2.

    US Treasury sanctions Myanmar militia group for alleged crypto scams
    The United States Department of the Treasury has sanctioned a Myanmar militia group known as the Karen National Army (KNA), accusing it of crypto-related scams and other criminal activities. According to a May 5 press release issued by the agency, the Karen National Army has been orchestrating a variety of crypto scams, including the infamous “pig butchering” scam, which lures victims into contributing more and more to fake crypto schemes. Americans “have collectively lost billions of dollars” from scams such as those emanating from Myanmar, the release reads, without specifying an amount. “Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned the Karen National Army (KNA), a militia group in Burma, as a transnational criminal organization, along …
    VanEck files for BNB ETF, first in US
    Asset manager VanEck has asked US regulators for permission to list an exchange-traded fund (ETF) holding BNB, the native token of Binance’s BNB Chain, regulatory filings show.  The ETF is designed to accumulate spot BNB (BNB) tokens and “may, from time to time, stake a portion of the [fund’s] assets through one or more trusted staking providers,” according to the ETF’s S-1 prospectus. The filing marks the first time an asset manager has filed for a BNB ETF in the United States. The BNB token has a market capitalization of roughly $84 billion, according to data from CoinMarketCap. As of May 5, BNB stakers earn a yield of approximately 2.5%, according to data from Stakingrewards.com.  Binance’s BNB Chain is among the most popular smart contract networks, with a total value locked (TVL) of n…
    What do crypto users want to happen to Alex Mashinsky?
    Crypto users are weighing in as Alex Mashinsky, the former CEO of Celsius Network, prepares to stand before a judge on May 8 to face sentencing for commodities fraud and a fraudulent scheme to manipulate the price of the platform’s token. In a May 2 filing in the US District Court for the Southern District of New York (SDNY), prosecutors released several impact statements from individuals affected by the collapse of Celsius filed after the initial deadline. Though at least one suggested clemency for the former CEO, many told the court about the financial and personal losses caused by the crypto firm filing for bankruptcy, and hinted that Mashinsky should be held accountable for misrepresenting the company. “Many of the people who participated in this fraud, benefited from this fraud, and p…
    Price predictions 5/5: SPX, DXY, BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI
    Key points: Bitcoin is witnessing a tough battle between the bulls and the bears at the $95,000 level. Solid buying by spot Bitcoin ETF investors last week signals a positive shift in investor sentiment.  Select altcoins have held their support levels, increasing the likelihood of a short-term up move. Bitcoin (BTC) slipped below the breakout level of $95,000 on May 4, indicating profit booking at higher levels. The bulls tried to push the price back above $95,000 on May 5 but are facing stiff resistance from the bears.  Glassnode senior researcher CryptoVizArt said in a post on X that Bitcoin maintaining above $93,000 was very surprising and also risky as the rally to the $93,000 to $96,000 range “pushed the profit-taking volume above the statistical levels.” CryptoVizArt added that t…

    What will Bitcoin price be if gold hits $5K?
    Key takeaways: Bitcoin has historically outperformed gold, more recently by sixfold. Gold’s climb toward $5,000 could set the stage for significant Bitcoin gains. Weakening US dollar and rising global liquidity remain key drivers for both assets. Gold’s march toward $5,000 per ounce and beyond has become a big topic among hard-asset bulls, including Yardeni Research’s head Ed Yardeni and billionaire investor John Paulson. But what could happen to the price of Bitcoin (BTC), touted as “digital gold” by many, if the precious metal surges even higher? BTC price jumped 6x last time gold rallied Bitcoin has historically delivered far more substantial gains than gold when their markets rally concurrently.

    Crypto market manipulation schemes are becoming increasingly coordinated
    Opinion by: Tracy Jin, Chief Operating Officer, MEXC Market manipulation is everywhere and yet nowhere to be seen. It is an invisible threat affecting crypto and traditional markets, leaving ordinary traders counting the costs. Sometimes, manipulation is obvious — illiquid tokens being pumped high before being dumped just as fast — but often, it's subtler and more challenging to detect. What's more concerning is that these schemes are no longer the domain of rogue whales or amateur pump groups. Signs increasingly point to highly organized, well-funded networks coordinating activities across centralized exchanges, derivatives platforms, and onchain ecosystems. As these actors grow in sophistication, their threat to market integrity expands exponentially. A tale as old as time  Market manipu…
    Ripple commits $25M US school nonprofits
    Ripple, the US-based crypto services firm behind the XRP Ledger, has committed $25 million in Ripple USD (RLUSD) to education nonprofits DonorsChoose and Teach For America. According to a May 5 announcement, the grant will be processed through the crypto charity intermediary service The Giving Block. DonorsChoose CEO Alix Guerrier said "teachers are going the extra mile for their students' education, even spending hundreds — sometimes thousands — of dollars out-of-pocket for their classrooms." The donations are meant to provide teachers with resources for such initiatives. Ripple cites a 2024 Gallup survey showing that 55% of US parents and adults are dissatisfied with the quality of K-12 education in the United States. This highlights “constraints and gaps in funding for education,” the reports reads. Ripple CEO Brad Garlinghouse said in the statement: “We hope to inspire others to do the same, starting with Teacher Appreciation Week, and leading into the rest of the year to support students and teachers with the resources they need to build a stronger future for themselves and their communities.” Teach For America CEO Aneesh Sohoni said the new funding will allow the organization to expand its “Ignite Tutoring Fellows program, drive innovation in our Reinvention Lab, and provide crucial financial assistance” to prepare teachers. Related: The Giving Block starts disaster fund for California wildfire victims Crypto-fueled charity The cryptocurrency industry is familiar with charitable donations. Last month, Binance co-founder Changpeng “CZ” Zhao pledged over half a million dollars worth of crypto to the earthquake disaster relief effort in Thailand and Myanmar.

Another player in the crypto charity field, Blockchain For Impact (BFI), in March committed $90 million to advance biomedical research. Magazine: 6 Questions for Alex Wilson of The Giving Block
    How a $243 million crypto heist led to a real-world kidnapping

    Trump to host memecoin gala dinner amid backlash, impeachment calls
    US President Donald Trump will host a gala dinner for top holders of his Official Trump (TRUMP) memecoin despite bipartisan criticism and renewed calls for impeachment. In a May 5 Truth Social post, Trump announced that he will hold a gala dinner with major TRUMP holders on May 22. The announcement follows multiple US lawmakers expressing concern over the initiative. In late April, Massachusetts Senator Elizabeth Warren called on government officials to address questions related to Trump’s memecoin and his media company. Controversies grew after Trump announced a dinner and White House tour for some holders of his TRUMP memecoin. “President Trump’s announcement promises exclusive access to the presidency in exchange for significant investment in one of the President’s business ventures,” a…

    Aptos exec sees Web 2.5 platforms earning ‘tons’ of revenue
    While many crypto ecosystems focus on decentralization as the core tenet of Web3, Aptos is seeing success with hybrid platforms that blend Web2 and Web3 technologies, commonly referred to as “Web2.5.” In an interview at the Token20249 event in Dubai, Aptos’ head of ecosystem, Ash Pampati, told Cointelegraph that they see Web2.5 platforms earn “tons of revenue” within Aptos. He noted that consumer-focused applications in particular are thriving on the network. Web2.5 is a term used to describe a combination of Web2 and Web3 technologies. The term describes platforms or applications that blend centralized Web2 experiences with decentralized Web3 elements.  These applications often avoid full decentralization, drawing criticism for not fully embracing the Web3 vision.

    Vitalik Buterin says rollups must prove security before decentralizing
    Ethereum co-founder Vitalik Buterin has explained when he believes rollup-based layer-2 platforms should go decentralized, and why “as soon as possible” is not the correct answer. In a May 5 X post, Buterin explained that there is a right time for rollup-based scalability solutions to transition to a decentralized model. This moment depends on how low the proof system’s failure probability has fallen compared with the risks introduced by centralization. Buterin’s thread came in response to a separate post by decentralized exchange Loopring founder and CEO Daniel Wang. Wang explained in his thread that the maturity of a system matters to its security: “Not all code is created equal.

    America’s crypto renaissance is already failing; but we can fix it
    Opinion by: Shane Molidor, Founder, Forgd For years, launching a crypto project in the United States has been a maze of uncertainty. Legal ambiguity and a hostile regulatory environment have driven founders offshore, turning places like Switzerland and the Cayman Islands into global hubs for blockchain innovation.  With Trump’s election, things finally started to change, with a US administration openly declaring its intention to be crypto-friendly. Yet, despite the rhetoric, nothing concrete has changed so far. Launching a crypto project in the US is just as difficult as ever.

    How cybercriminals are exploiting digital twins to scam crypto users
    What is a digital twin? A digital twin is a virtual model or replica of a physical object, system or process. It’s like a digital mirror, allowing us to simulate, monitor and predict the behavior of real-world entities in real-time.  These virtual counterparts are designed to pull data from physical sensors or inputs, providing a continuous feedback loop that helps with analysis, optimization and decision-making. Digital twins can represent almost anything, from machinery in a manufacturing plant to human behavior or entire cities. In industries like healthcare, automotive, manufacturing and urban planning, digital twins allow for better resource management, predictive maintenance and more accurate simulations before physical changes are made.

    Donald Trump gives conflicting answers over memecoin profits
    US President Donald Trump gave clashing answers to whether he has profited from the crypto memecoin he launched in January, just days before he re-entered the White House. In a wide-ranging interview with Kristen Welker on NBC News’ Meet the Press released on May 4, Trump said he was “not profiting from anything” when asked to respond to critics who said he’s profiting from the presidency through the memecoin. “So you’re not profiting off of the cryptocurrency at all?” Welker asked Trump. “I haven’t even looked,” Trump admitted. “But I’ll tell you what. Look, if I own stock in something and I do a good job, and the stock market goes up, I guess I’m profiting.” Trump launched his memecoin, Official Trump (TRUMP), on Jan. 17, which hit a peak of $73.43 two days later, just a day before he wa…

    Spot Bitcoin exchange-traded funds (ETFs) in the United States bought up nearly six times as many Bitcoin as were produced by miners over the last week. The US-based Bitcoin (BTC) funds bought a whopping 18,644 Bitcoin over the past week when only 3,150 BTC were mined for the period, reported asset allocator HODL15Capital on May 4. This accumulation by institutions and ETF issuers represents almost six times the amount of the asset being produced since miners only generate 450 coins per day.   The total inflow for the past five trading days was around $1.8 billion, with a net outflow on April 30, according to Farside Investors. There has only been one outflow day since April 16, as the inflows have mirrored market recovery.  Last week’s accumulation followed an increase in BTC spot prices …
    OpenAI ignored experts when it released overly agreeable ChatGPT
    OpenAI says it ignored the concerns of its expert testers when it rolled out an update to its flagship ChatGPT artificial intelligence model that made it excessively agreeable. The company released an update to its GPT‑4o model on April 25 that made it “noticeably more sycophantic,” which it then rolled back three days later due to safety concerns, OpenAI said in a May 2 postmortem blog post. The ChatGPT maker said its new models undergo safety and behavior checks, and its “internal experts spend significant time interacting with each new model before launch,” meant to catch issues missed by other tests. During the latest model’s review process before it went public, OpenAI said that “some expert testers had indicated that the model’s behavior ‘felt’ slightly off” but decided to launch “du…
    Hackers use New York Post’s X account to send scam DMs, users report
    Malicious actors appear to have infiltrated the New York Post’s X account in an attempt to scam crypto users on the microblogging platform.  Some X users from the crypto community have recently reported having received a private message from the New York Post’s X account inviting them to feature in a podcast and to contact them via Telegram.  The spurious messages were first discovered on May 3 by Kerberus founder and CEO Alex Katz, who shared a screenshot of a message made out to be from author and journalist Paul Sperry via the official nypost account.  “What’s interesting about this case is that the scammer gained unauthorized access but didn’t post a Pump.fun address or wallet drainer. Instead, they’re messaging users and then directing them to Telegram,” observed cybersecurity enginee…
    Solana devs fix bug that allowed unlimited minting of certain tokens
    The Solana Foundation has confirmed that a zero-day vulnerability that allowed an attacker to potentially mint certain tokens and even withdraw those tokens from user accounts has been fixed.  A May 3 post-mortem from the Solana Foundation said that the security vulnerability, first discovered on April 16, could have allowed an attacker to forge an invalid proof affecting Solana’s privacy-enabling “Token-22 confidential tokens.” There is no known exploit of the vulnerability, and Solana validators have since adopted the patched version, the foundation said. Solana zero-day security bug affected Token-22 confidential tokens The Solana Foundation said the security vulnerability concerned two programs: Token-2022 and ZK ElGamal Proof.

The company said it will decide on the “long-term future” of Mattel digital collectibles. “Your unwavering support and enthusiasm for the Hot Wheels Virtual Garage has been legendary, and we’re incredibly grateful to have been on this journey with you,” the company said. “As we evaluate the changing world of virtual collectibles, we’ve determined the time has come to end our Series and Feature Drops in 2025 and onward.” There are no plans for any new NFT series or feature drops for Mattel's Hot Wheels Virt…
    Bitcoin price cools going into Fed rate hike week, HYPE, AAVE, RNDR, FET still look bullish
    Key points: Bitcoin’s positive sentiment should remain intact if BTC price stays above the 20-day EMA near $92,000. Several altcoins show bullish chart patterns in the 4-hour and 1-day timeframes. Bitcoin (BTC) has given back some of the gains over the weekend, and the price has pulled back to the breakout level of $95,000. Buyers will have to successfully hold the $95,000 level to keep the bullish momentum intact. Bitcoin network economist Timothy Peterson said in a post on X that Bitcoin could surge to a new all-time high and reach a target of $135,000 in the next 100 days if certain conditions are met. Peterson believes a drop in the CBOE Volatility Index below 18 could trigger a “risk-on environment” favoring Bitcoin. The other crucial points needed for the Bitcoin rally are a fall …

    Rebuilt in 3 Days: DMs Are Back — and Better Than Ever
    Originally posted on May 2, 2025 After a major setback wiped our codebase, we rebuilt Tavrn's 1-to-1 DM system from scratch — in just 3 days. This post breaks down how we did it, what’s new, and why it’s already better than before. After losing our original codebase, we had two choices: Start over slowly and mourn the loss... Or hit the ground running and build something better. We chose the second one. It only took 3 days — but our 1-to-1 messaging system is back. Fully rebuilt from the ground up. Clean. Fast. Future-proof. And, honestly? It’s better than what we had before. We redesigned how messages move, how conversations flow, and how it all scales. What used to feel basic now feels tight — like something you’ll actually want to use every day. Here’s a little peek at what’s already working in our new DM system: 🔒 Fast messaging with improved delivery speeds 🌙 Sleeker UI built with clarity and vibe in mind 🗂️ Better message rendering 💬 Typing indicators and presence detection, redone the right way ⚡️ A system that can grow without getting messy And we’re just getting started. Now that DMs are locked in, we’re moving on to polish other core features — including group chats, profiles, and real-time updates. Every step is built with community, performance, and personality in mind. No bloat. No noise. Just smooth, satisfying conversation. Setbacks happen. But we’re proud of how we responded: By building. By improving. By actually shipping something better. If you’ve been waiting on Tavrn — thank you. The foundation is back. And the future’s right behind it. — Tavrn  ( 3 min )
    Intelligent Retail
    Shopping—a timeless ritual familiar to us all—is quietly undergoing a profound transformation. Gone are the days when shopping was nothing more than exchanging goods for currency. Today, beneath the familiar surface of the high street and online storefronts, an intricate interplay of data-driven intelligence and personalised precision shapes the retail landscape. At the epicentre of this quiet upheaval is Artificial Intelligence (AI). Not a futuristic novelty from distant sci-fi narratives, but a living, evolving presence within retail operations worldwide. By 2025, AI’s role in retail is forecasted to be valued at an astounding £54.92 billion. A recent Gartner report underscores its importance starkly: 91% of retail IT leaders now regard AI as a core strategic priority. AI, it seems, has …  ( 6 min )
    Agendas lead to more productive meetings
    I have been in team meetings where, they were basically, "free-form discussions." We'd start with good intentions, but two hours later, no real decisions have been made. It was frustrating, and the team's energy was draining with each meeting. The problem? We needed structure, not just good intentions. So, we started implementing detailed agendas for every meeting. At first, it felt a bit rigid, but then with time, our two-hour meetings actually ended in 45 minutes or less. People came prepared. Decisions were made faster. But here's the thing - it's not just about having an agenda. It's about crafting one that guides the conversation without stifling creativity. We found a balance between structure and flexibility with Rally. This experience played a huge role in why you can build agendas from your Jira board with Rally.

    Does Your Coding Machine's OS Really Matter? My Windows-to-Linux Journey
    As someone who jumped from Windows to Linux, I've found that your choice of operating system can definitely impact your coding life - but it's not make-or-break. Linux gives me a better command line, simpler software installation, and runs lighter on my hardware. I especially love how it matches most production servers, making deployment way less headache-inducing. That said, Windows isn't the villain some developers make it out to be. It plays nicer with commercial software, gaming tools, and corporate systems. Windows users now have a solid option with WSL (Windows Subsystem for Linux), letting you run Linux tools right inside Windows - giving you the best of both worlds without the commitment of switching entirely. Ultimately, great developers build amazing stuff on all systems. Your OS is just one piece of your toolkit, not the defining factor of your skills. My switch to Linux boosted my workflow for web and backend projects, but I know plenty of rockstar devs crushing it on Windows and Mac. What's your setup?

    Building AI Pipelines Like Lego Blocks: LCEL with RAG
    Building AI Pipelines Like Lego Blocks: LCEL with RAG The Coffee Machine Analogy Imagine assembling a high-tech coffee machine: Water Tank → Your data (documents, APIs, databases). Filter → The retriever (fetches relevant chunks). Boiler → The LLM (generates answers). Cup → Your polished response. LangChain Expression Language (LCEL) is the instruction manual that snaps these pieces together seamlessly. No duct tape or spaghetti code—just clean, modular pipelines. LCEL lets you build production-ready RAG systems with: Retriever → Searches your vector DB (like a librarian). Prompt Template → Formats the question + context for the LLM. LLM → Generates the answer (e.g., GPT-4, Claude). Output Parser → Cleans up responses (e.g., extracts text, JSON). Turn your vector DB into a sea…  ( 4 min )
    Why Does Using '==' Cause an Error in Kotlin with ExitStatus?
    In Kotlin, it’s common to encounter various types of comparison errors, especially when dealing with Java classes due to interoperability issues. The issue you're experiencing occurs when trying to compare an instance of the ExitStatus class from Spring Batch using the ==</code operator. Understanding the Comparison in Kotlin Kotlin has a distinct approach to equality compared to Java. In Kotlin, the == operator is actually syntactic sugar for the equals() method. Thus, when you write if (jobExecution.exitStatus == ExitStatus.COMPLETED), Kotlin attempts to call equals() on the jobExecution.exitStatus. However, if Kotlin does not recognize ExitStatus as having a valid equals method that matches the expected types, you will receive the compilation error: No method 'equals(Any?): Boolean' av…  ( 4 min )

    Access Control Lists in Linux for Granular Permissions (Day 11 of 30)
    Table of Contents Introduction Why Traditional Permissions Fall Short What Are ACLs and When to Use Them Basic ACL Commands: getfacl and setfacl Real-World Examples Removing and Managing ACLs Best Practices Summary In Linux, we usually use chmod and chown to manage file permissions. That works well when you just need to give access to one user and one group. But what if you need to give access to multiple users or different groups on the same file? That's where ACLs (Access Control Lists) come in. They allow you to control file access in a much more detailed way. Standard permissions only allow: One owner (user) One group Let’s say you want to: Give read-only access to one user Allow full access to another user And block a group from accessing the file You can’t do this wi…  ( 4 min )
    Why Is AWS CLI Ignoring Includes When Running in Bash?
    Introduction If you've found yourself wondering why the AWS CLI ignores --include options when you run a complex command through a Bash script, you're not alone.

    The Most Subtle Bug approved in a PR
    ✅ Reviewed PR The most subtle bugs aren't in the code you write - they're in the code you approve without enough context. This is a short story about a seemingly harmless line in a PR that I reviewed - and how it taught me to slow down, even with small changes. The line of code below, if(!user.isVerified) return; intention behind this was good not to allow unverified users to proceed into the app. But this return statement wasn't part of larger flow. It was inside a route guard - and it exited silently, without a redirect, message or error. User who signed up with Google or Github (OAuth) were marked isVerified=false This line caused the app to fail to load the protected dashboard, but displayed no error The app just failed silently with blank screen to user. A fallback route with clear message was added and tested both social and email/password flows going forward. if(!user.isVerified) { this.route.navigate(['/verify-email']); return; } 🧠 Real world dev lesson from more than a decade of experience 💬 I'd love to hear your most unexpected regrets too  ( 3 min )

    How to Use Reference and Output Parameters in Java
    Introduction In programming, passing parameters to functions is crucial for manipulating data effectively. Java, unlike some languages such as C#, does not support reference parameters in the same way. Instead, Java uses pass-by-value semantics, which means that when you pass a variable to a method, a copy of that variable is sent. However, there are ways to achieve similar functionality using mutable objects or wrapper classes. In this article, we'll explore how to simulate reference-like behavior in Java using simple examples and provide a clear understanding of handling output parameters in functions. Understanding Reference Parameters in Java When you define a method parameter in Java, it typically receives a copy of the variable's value.

    What does (*jsontext.Value)(&b).Indent() do in Go?
    When working with Go, handling JSON data is a common task. In the code snippet you're referring to, we see the use of a specific method: (*jsontext.Value)(&b).Indent(). This can be a bit confusing for those who are new to Go or JSON manipulation. So let’s break it down. Understanding JSON Marshaling in Go In Go, the encoding/json package is typically used to encode and decode JSON. In your example, b, _ := json.Marshal(output) marshals the output variable into a JSON byte slice b. The underscore _ is used to ignore any errors that may occur during marshaling. This is often a pattern when we are confident that there won't be an error or we want to handle it later. What is *jsontext.Value? The section (*jsontext.Value)(&b).Indent() involves a couple of key components. First, jsontext.Value i…  ( 4 min )

    How to Fix Incorrect 3D Projection in C with cglm?
    When working with 3D graphics, projecting a world position to screen space can sometimes lead to unexpected results, like the mirrored effect you're observing. This issue often arises from the way matrices—specifically the view-projection matrix—are combined when rendering a scene. In your code, you mention that the screen position moves in the opposite direction when you rotate the camera. Let's delve deeper into why this might be happening and how we can fix it effectively. Understanding the Problem In your code, you set up the view and projection matrices and then combine them to create a view-projection matrix. However, if the view matrix isn't correctly set up to reflect the camera's orientation, the resulting transformations can appear inverted or mirrored. To ensure proper functiona…  ( 5 min )

    Mastering Git Commit Messages with Conventional Commits
    ✳️ Why Should We Care About Commit Message Structure? In any software project, every small change made to the codebase is recorded in Git history. This history is not just a log of what happened — it's a crucial tool for tracking changes, collaborating with others, managing releases, and automating development workflows. It becomes hard to understand why a change was made Generating changelogs becomes manual and time-consuming CI/CD tools can’t effectively leverage the commit history And in team environments, others struggle to follow your changes This is where Conventional Commits come into play. It’s a simple but powerful convention that allows us to write commit messages in a structured, readable, and machine-parsable way — making life easier for both developers and tools. 🧠 What is Co…  ( 4 min )
    Debugging @Scheduled Tasks in Spring Boot Without Sending Harassing Emails
    Recently in enterprise development, I came across a requirement to adjust and optimize a scheduled email-sending task. While the logic itself was straightforward, the debugging experience was not. Here's what made it tricky: The development environment lacks a unified interface to manually trigger backend @Scheduled tasks from the frontend. Debugging by modifying the cron expression means: Restarting the entire project every time Risking a flood of unintended emails While test code can directly invoke methods, it's not always clean or convenient. Let’s look at the scheduled task: @Component public class EmailScheduled { @Scheduled(cron = "0 0 23 * * * ?") public void emailSend() { // Actual email sending logic } } afterPropertiesSet to Trigger the Task The idea is simple: leverage the InitializingBean interface. Spring will automatically call afterPropertiesSet() when initializing a bean. So we can invoke emailSend() there to simulate a scheduled run. @Component public class EmailScheduled implements InitializingBean { @Scheduled(cron = "0 0 23 * * * ?") public void emailSend() { // Actual email sending logic } @Override public void afterPropertiesSet() throws Exception { emailSend(); // Triggered once at startup } } No cron modification No project restart just to adjust time No actual scheduling triggered — just one-time manual invocation Perfect for short-term debugging during development This is not meant to be a long-term solution. Remember to remove or disable this hack before deploying to production. For a more robust setup, consider exposing your scheduled tasks through an admin/debug endpoint or using Spring Boot Actuator with proper security controls.  ( 3 min )

    Amazon DocumentDB != Microsoft DocumentDB extension for PostgreSQL
    My next post will be about Amazon DocumentDB and how it compares to MongoDB in terms of indexing a flexible schema with multiple keys. There's a lot of confusion today with the "DocumentDB" name because earlier this year Microsoft announced DocumentDB: Open-Source Announcement which has nothing to do with Amazon DocumentDB. Amazon DocumentDB is a managed NoSQL database service that supports document data structures and is compatible with MongoDB versions 3.6, 4.0, and 5.0. It allows users to store, query, and index JSON data. Its storage capabilities resemble those of Amazon Aurora, featuring compute and storage separation, a monolithic read-write node, up to 15 read-only replicas, and multi-AZ storage.

    How to Keep TextInput Value in Dart when Dismissing Keyboard
    When building applications with Dart and Flutter, you might come across the frustrating issue of losing data on a TextInput field when the keyboard is dismissed. This typically occurs because the state of the input field is not being managed correctly. By utilizing a TextEditingController, you can ensure that the value users type into the text field remains intact even after they click 'Ok' or use the back button to hide the keyboard. Understanding TextEditingController In Flutter, a TextEditingController is an object that can be used to control a text field. It helps in retrieving the current value of the text field, listening to changes, and manipulating it. If you don’t initialize a TextEditingController, the text field will not maintain its state after interactions. Why the Value Disap…  ( 4 min )

    Clean Code Is a Habit, Not a Talent
    A smart developer once said: "Clean code isn’t some magic skill — it’s just a habit you build over time." And guess what? You can totally build that habit. Clean code means writing code that's clear, organized, and easy to work with. It makes your life (and your teammates’ lives) way easier. But let’s be honest — how many times have we said, “I’ll clean this up later”? Here’s the truth: There’s never a perfect time to refactor Messy code turns into technical debt — and sooner or later, you’ll have to deal with it. It’s better to start clean than to fix bugs forever later. Writing clean code isn’t as hard as it sounds. Actually, it can feel really natural once you get the hang of it.

    From Java to Go: Why Composition is Preferred Over Inheritance
    What Drives New Languages Like Rust and Go to Embrace Composition and Abandon Inheritance? Java has a guideline: “Don’t use inheritance unless you have a good reason.” But Java doesn’t strictly limit inheritance — you can still use it freely. Go, however, is different: it only allows composition. So why do modern languages promote composition? Actually, it’s not just new languages — even the veteran Java mentions in Item 16 of Effective Java: “Favor composition over inheritance.” Inheritance is a powerful way to reuse code, but it may not be the best method. So it’s worth thinking this through carefully. Without diving into specific code, let's talk about the concepts.

Demo https://permit-frontend-oafvwri0e-navankurusersessionmanagement.vercel.app/ Project Repo Using Permit.io for Authorization 🔐 Used @permitio/sdk in a centralized permit.js file 🧠 Implemented checkPermission() and assignRole() functions in a custom service layer 🛠️ Integrated with Express backend via role-based API routes (/assign-role and /check-permission) 🔁 Roles (admin, manager, etc.) and resources (workspace:123) are dynamically registered and queried using the Permit.io cloud PDP Permit.io helped me implement real RBAC and ABAC logic faster than building an in-house system — and with way more confidence. Shoutout Thanks to the Permit.io team for enabling builders like me with a tool that makes fine-grained access control actually practical. This was more than a submission — it was a step toward building better, safer, and more intentional apps. ** Team Members** Solo+AI Submission – built with passion and pain (and a little help from AI ❤️)  ( 3 min )

    ☁️ Keep Using AWS as Usual
    Hiya 👋! So, it's Sunday, homeboy, and I usually escape debates and negative thoughts. But today, I was scouring dev.to and stumbled across a post boldly titled "Stop Using AWS." It wasn't the first time I'd seen a call to drop Amazon Web Services for something "simpler", but this one hit a nerve, not because it was provocative, but because it misrepresents why AWS exists and what problems it solves. So, I decided to sit back, relax, and explain why you should absolutely keep using AWS, especially if you're serious about software, scalability, and sustainability. The post opens with a classic anecdote: a developer builds an MVP with all the AWS bells and whistles, Lambda, API Gateway, Cognito, S3, DynamoDB, and no one uses it. The conclusion? AWS was overkill. But let's be honest: blaming …  ( 7 min )

    Foundational Project Structure for .NET Projects
    A well-thought-out project structure is one of the most critical aspects of your project. It sets the foundation for how scalable your application will be in the long run. The higher up you go in the structural hierarchy, the more important it is to get it right from the beginning. Mistakes at the top can lead to bad practices and cost you later on. Lower-level decisions (like file or folder organization within a feature) offer more flexibility—it's less painful. Adjusting or removing a single leaf from a tree doesn't impact the whole tree, but doing the same with the entire branch can affect all its sub-branches and leaves. Similarly, changing the fundamental structure of a real-world system is never easy, it's usually extremely risky and time-consuming, so investing in a solid foundatio…  ( 6 min )

    Building a CLI for Multi-Agent Tree-of-Thought: From Idea to Execution - Part 1
    What if LLMs had opinions and argued in threads? What happens when we give LLMs not just memory and tools, but also autonomy, voices, perspectives, and structure? I built a simple CLI tool, a tiny experiment in multi-agent, tree-of-thought reasoning. The tool lets you simulate a conversation between different AI personas, each contributing their thoughts in a threaded format. This concept of enabling language models to work together to solve complex problems, with each agent assuming a unique role based on its strengths, is a central tenet of multi-agent LLM systems. Such systems are often observed to outperform traditional single-agent models, particularly when dealing with intricate tasks that necessitate diverse expertise and collaborative decision-making.

    You Should Encrypt Your Environment Variables 🔑
    Environment variables (.env files) are a popular way to manage configuration and secrets in modern applications. leaving these files unencrypted exposes critical API keys, database credentials, and other sensitive data to risk. In this post, we’ll explore why encrypting your environment variables is essential, introduce dotenvx—a lightweight CLI for encrypting/decrypting your .env files—and compare it with other industry-standard methods for secret management. Version Control Exposure: Accidentally committing .env files can leak secrets publicly (e.g., GitHub incident examples).

    Kubernetes Troubleshooting in the Cloud
    Kubernetes has been used by organizations for nearly a decade – from wrapping applications inside containers, pushing them to a container repository, to full production deployment. At some point, we need to troubleshoot various issues in Kubernetes environments. In this blog post, I will review some of the common ways to troubleshoot Kubernetes, based on the hyperscale cloud environments. Before we deep dive into Kubernetes troubleshooting, let us review some of the common Kubernetes errors: CrashLoopBackOff - A container in a pod keeps failing to start, so Kubernetes tries to restart it over and over, waiting longer each time. This usually means there’s a problem with the app, something important is missing, or the setup is wrong. ImagePullBackOff - Kubernetes can’t download the c…  ( 6 min )

    Vibe Coding — My Simple Way to Enjoy Coding More 🌿💻
    Hey there! 👋 Let’s talk about something I love to call vibe coding. No, it’s not a new framework or tool.

    Using nanostores in Astro + Vue setup
    Written by Nabil It's 2025 and Astro is a growing framework. In this quick post, I'd like to share a little bit about my little workaround when I was building my personal website for the first time. Astro has a static-first architecture and I was going to use it without its on-demand SSR feature. So just for a note, this means I couldn't use Astro session that could've been handy for operating states handled by server. Meanwhile, I also used Vue.js alongside Astro with its integration portability (sorry if it looks like I am doing an experiment here, yes I'm still learning). Everything went well until I encountered something in a Vue component that needs the Astro's context object. Say that you need Astro.url. This URL-object property can only be accessed in Astro's render context object:…  ( 4 min )

    Qwen 3 vs. Deepseek R1: Complete comparison
    Introduction The Alibaba recently team has released the Qwen 3 Series, including two standout models: the 235B parameter MoE model (with 22B active parameters) and a lightweight 30B version (3B active). As per official docs, the Qwen3-235B-A22B model take on giants like DeepSeek R1, Grok-3, and Gemini 2.5 Pro—and it is doing it with fewer active parameters, faster inference, and open-source accessibility. On the other hand, on a lighter note the Qwen3-30B-A3B outcompetes the previous QwQ-32B with 10 times of activated parameters, and a small model like Qwen3-4B can rival the performance of Qwen2.5-72B-Instruct. Best part, takes fraction of cost per million input and output token, compared to SOTA models. Impressive, isn’t? Alibaba released Qwen 3, featuring efficient MoE models (235B …  ( 14 min )
    May the Nodes Be with You
    Knowledge graphs are powerful tools to visualize and explore your data, and can help uncover new insights and patterns in how your data is related. They are easy to search and navigate, but getting your data into the graph database in the right format can be challenging. And the resulting graph is only as good as the data--- or as they say, garbage in, garbage out. So it's important to define a good schema, or ontology, that describes the entities and relationships you want to extract from your data. With unstructured text, you can use an LLM to extract entities and relationships, and then generate a Cypher query using the model (guide). This can take a lot of the work out of generating the Cypher queries but it comes with the risk of hallucinations, and the security and privacy concerns o…  ( 7 min )

    Podman: Detailed Overview, Advantages, Disadvantages, and Setup
    Podman is an open-source container engine that enables users to create, manage, and run OCI containers and pods across Linux, macOS, and Windows. Unlike Docker, Podman is daemonless, running containers directly under the user's control, which brings unique benefits in security and flexibility. Daemonless Operation Podman does not require a central background service. Each container runs as a child process of the user, reducing resource overhead and improving security by eliminating a single point of failure. Rootless Containers Podman supports running containers without root privileges. This greatly reduces the risk of privilege escalation and is ideal for multi-user systems or environments with strict security requirements. Docker Compatibility Podman’s command-line interface is largel…  ( 5 min )

    Who Controls Your Files in Linux? Discover the Power of Permissions 🔐
    When working in a multi-user Linux environment, not everything is open to everyone—and that’s for a reason. File permissions are a cornerstone of Linux security, ensuring that only the right people can access or modify critical files. Whether you're a budding sysadmin or a curious developer, understanding how Linux handles file access is crucial to maintaining control and security. Let’s break it down 👇 Linux file permissions determine who can read, write, or execute files and directories. Each file or directory is governed by three levels of access: Owner (User) – The creator of the file. Group – Users who belong to the assigned group. Others – Everyone else. Permissions are represented in two ways: Read (r or 4) – View file contents. Write (w or 2) – Modify file contents. Execute (x or …  ( 4 min )

    Scripting Series – Part 6 of 8
    Here we will dive into part 6 in the shell scripting series. Today we will look at how you can use a for loop to iterate through all files in a directory and the function of file comparison. Shell scripting is essential in production environments for automating repetitive tasks, ensuring consistency, and minimising human error. It enables engineers to streamline deployments, manage system configurations, monitor processes, and orchestrate complex workflows with precision. In a high-availability environment, shell scripts act as reliable, lightweight tools that reduce manual intervention and improve operational efficiency. Create the script using VIM. Write the script in VIM and save the file. Apply the necessary permissions to the script so it can be executed. If we do a ls –ltrh we see that the script has been created. It has a green colour to it – indicating that it is now executable. Execute the script using ./ The output of the script, after it has been executed. Stay tuned, part 7 in the series coming tomorrow!

    Turn any photo into a color palette – made a tool for designers & artists
    Hey everyone! I’m a designer/developer who’s always hunting for the perfect color palette, and I got tired of manually picking colors from images. So, I built a free web tool that lets you upload any image (or use a sample), and it instantly gives you a palette of the most important colors – in HEX, RGB, HSL, etc. You can choose between different extraction methods (Vibrant, Material Design, Median Cut, K-Means) depending on what kind of palette you want. It works right in your browser, and nothing gets uploaded to a server. Try it here: https://colorsfromimage.xyz/ Would love to hear what you think! Is it useful for your workflow? Any features you wish it had? Found any bugs or weird results? I’m open to all feedback, and if you make something cool with it, please share! Thanks for checking it out :) Robert  ( 3 min )
    Building Dcup: An Open-Source RAG Pipeline with a Twist
    Ever wrestled with a RAG pipeline and thought, “Why is this so damn hard?” We’ve been there—tearing our hair out over complexity and slow performance. So, I built Dcup, an open-source, self-hostable RAG-as-a-Service platform that actually works Very good. It’s a tool to hook your app up to user data with zero bullshit. Here’s the rundown: Tech Stack: Next.js, BullMQ for job queues, OpenAI for embeddings, and Qdrant for vector storage. It’s lean, mean, and scales like a dream. Killer Features: AI-driven retrieval and hybrid search that cuts through the noise. Plus, optional re-ranking if you’re a precision freak. Learn more At its core, Dcup is your bridge to smarter data handling. It takes the complexity out of RAG pipelines by automating the heavy lifting. Here’s how it works in plain English: Data Ingestion: Hook up your data sources—think Google Drive, AWS, or wherever your files live—and Dcup keeps it all synced and current. Data Processing: Your raw data gets chopped into bite-sized chunks and turned into embeddings using OpenAI. (More on embeddings later—they’re cool!) Storage & Indexing: Those embeddings land in Qdrant, a lightning-fast vector database that makes searching a breeze. Advanced Retrieval: Need answers fast? Features like re-ranking and hybrid search dig up the most relevant info in seconds. Think of Dcup as your personal AI assistant that organizes, understands, and retrieves your data like a pro. Big files used to choke us. Performance would tank, and we’d be staring at spinning wheels. Then we got smart—batching and parallel processing turned it around. Now, Dcup eats large datasets for breakfast. This isn’t some corporate ad. It’s a project by dev not shitty vibe coding or whatever the kids call it these days. Star the repo if it vibes with you: Dcup on GitHub. Wanna contribute? Hit me up! Let’s make RAG pipelines suck less together.  ( 4 min )

    9 OOP Design Patterns You Must Know
    9 OOP Design Patterns You Must Know A-Creational Patterns Deal with object creation mechanism to decouple the client code from concrete classes. Factory Pattern: Centralizes object creation logic and returns different subclasses based on input Singleton Pattern: Ensures only one instance of a class exists and provides global access to it. Builder Pattern: Constructs complex objects step-by-step, allowing optional configuration. B - Structural Patterns Help compose classes and objects into larger structures. Adapter Pattern: Allows incompatible interfaces to work together by translating one interface into another. Decorator Pattern: Adds new behavior to objects dynamically without altering their original structure. Proxy Pattern: Acts as a placeholder for accessing another object. C - Behavioral Patterns Focus on communication and interaction between objects. Strategy Pattern: Allows selecting an algorithm or behavior from a family of interchangeable strategies at runtime. Observer Pattern: Enables a one-to-many dependency so that when one object changes state, all its dependents are notified. Command Pattern: An object encapsulates all information needed to perform an action or trigger an event. Over to you: Which of these patterns have you used?  ( 3 min )

    🔌 Accessing Localhost from the Internet – Simple Tunneling Tools
    When you're building a web app on your local machine, sometimes you need to share it with someone online — maybe a teammate, client, or even for testing on your mobile device. But localhost only works on your computer. That’s where tunneling tools come in! They create a secure public URL that maps to your local server. Below are three popular options: Website: https://ngrok.com How it works: You run a command like ngrok http 3000 and ngrok gives you a public HTTPS link that forwards traffic to your localhost:3000. Pros: Very fast and reliable Works well with webhooks (e.g., Stripe, GitHub) Dashboard to inspect requests Cons: Free tier has time and region limits Requires an account after initial use GitHub: https://github.com/localtunnel/localtunnel How it works: npm i -g localtunnel Then run lt --port 3000 Pros: Super simple and open source No signup required Cons: Can be slower or less reliable than others Fewer features, no UI Docs: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/ How it works: cloudflared CLI and connect your app through Cloudflare. Pros: Very secure Great if you're already using Cloudflare DNS Free with more generous limits than ngrok Cons: Slightly more setup steps Best for advanced users or teams 🧠 Final Thoughts Just pick the one that fits your workflow and you're good to go!

    Words and numbers
    Weekly Challenge 319 Each week Mohammad S. Anwar sends out The Weekly Challenge, a chance for all of us to come up with solutions to two weekly tasks. It's a great way for us all to practice some coding. Challenge, My solutions You are given a list of words containing alphabetic characters only. Write a script to return the count of words either starting with a vowel or ending with a vowel. So vowels in English are a, e, i, o, u and sometimes y. It seems clear from the second example that even though weekly ends with a vowel, the task assumes that it is just the five letters. This task is a one liner, and simply counts the words that starts with a vowel letter or ends with one. def word_count(words: list[str]) -> int: return sum(1 for word in words if re.search('^[aeiou]', word) or re.search('[aeiou]$', word)) $ ./ch-1.py unicode xml raku perl 2 $ ./ch-1.py the weekly challenge 2 $ ./ch-1.py perl python postgres 0 You are given two arrays of integers. Write a script to return the minimum integer common to both arrays. If none found return -1. For the command line input, I take two strings and separate them on non-digit characters. My solution takes the two lists and converts them to sets and uses the intersection method & to get values that appears in both lists. If there is one or more values found it returns the minimum value. If none is found, it will return -1. def minimum_common(list1: list[int], list2: list[int]) -> int: intersection = set(list1) & set(list2) return min(intersection) if intersection else -1 $ ./ch-2.py "1, 2, 3, 4" "3, 4, 5, 6" 3 $ ./ch-2.py "1, 2, 3" "2, 4" 2 $ ./ch-2.py "1, 2, 3, 4" "5, 6, 7, 8" -1  ( 3 min )

    Building "Production-Grade" APIs in .NET
    Many engineers build and deploy APIs into production. So we have an API running in production — does that mean it’s truly production-grade? More often than not, the answer is no. We write the code, test it locally (usually alone, on one machine, with one user), and proudly tell the business, "Hey, it’s ready!" Maybe there’s even a QA environment where someone from product gives it a quick click-through and confirms, "Looks good to me!" And then... reality checks in. You get a call on the weekend: “Users can’t log in.” Or worse: “A customer placed an order, and it’s gone.” Now you're scrambling, thinking: “I wish I’d added logs there.” “Why didn’t we catch this earlier?” “How are we supposed to debug this in production?” If that scenario feels familiar, this post is for you.

    Basic Class and Object
    Lets start with basic example of banker problem to understand basic class and object Assume you want to create an account in SBI bank. So you fill that form and your account is created. Now you are the person who created that form. Which attribute or field you will create which is necessary to create an account. Lets say:- Name DOB Aadhaar card no. PAN Card no. class BankForm: __init__(userName,userDOB,userAdhaarNo,userPAN): Rohan=BankForm("Rohan","12-09-2025","xxxx8907","KB1234") you will find an error. why? Because the class doesn't know about the form. It mean that you are creating the form, but for whom. If you are thinking for SBI. Let me tell you they doesn't know. so how we are going to tell them. By using 'self'. class BankForm: __init__(self,Name,DOB,AdhaarNo,PAN): 'self' it just a way to tell SBI I have a form for you. Now you have heard some word like Instance, __init__ and object. Instance:- It is just like Rohan want form for himself.So you have to fill BankForm as in Instance. __init__:- Initialisation of object. Like you want to create form and decide field which is needed for the form. Like Name, DOB, AdhaarNo., PANNo.. Object:- simply it is the field.  ( 3 min )

    Finding Hidden Comic Book Deals: A TypeScript Scraping Solution
    🐙 GitHub Comic book collectors face a common challenge: getting the best value for their money. While the cover price is straightforward, the actual value can vary significantly when you consider the number of pages in each volume. A $20 comic might contain 100 pages, while another at the same price point offers 400 pages. To solve this practical problem, we'll develop a TypeScript program that calculates and compares the price per page, helping collectors make data-driven purchasing decisions. The complete source code for this project is available on GitHub. Using this approach, I bought four 400-plus-page comics for $85 total, including shipping costs.

    Forget uniqueness. Do marketing first.
    Forget uniqueness. Do marketing first. When I launched my idea — a simple SaaS for status pages — someone commented: “You're building the same thing that already exists. Where’s the uniqueness?” And honestly? That’s exactly why I decided to build it. The market already exists. Paying customers already exist. Can I sell it? Can I make money from it? That’s what really matters. There was a time when you could “build → launch → get traffic.” Now, product-first is a trap. Instead: Before writing a single line of code, I: Built a landing page explaining what the idea is, and who it's for Defined pricing (based on competitors and positioning) Started driving traffic Measured how many leads I could get Learned if I could "sell" the idea, even without a working product That’s the real funnel: find traffic → qualify leads → convert → check economics. Not “does the idea have demand?” I’m testing: Can I attract and convert leads in this market? Can I acquire users profitably? Can I turn this into a sustainable business? That’s the difference between a side project and an actual SaaS business. In a big enough market, there's room for dozens of products. Distribution > innovation Marketing > features If you can build a profitable funnel — traffic, conversions, retention — you win. That’s what I’m focused on.

    A Comprehensive Guide to Object-Oriented Programming (OOP) Concepts Introduction
    Object-Oriented Programming, commonly known as OOP, is a programming approach that organizes code around objects rather than actions. This paradigm has become a cornerstone in modern software development because it helps developers manage complexity, reuse code, and create scalable systems. In this article, we’ll explore the fundamental concepts of OOP—classes, objects, inheritance, encapsulation, abstraction, and polymorphism. By the end, you’ll have a clear understanding of these key principles and how they work together to create robust software. Let’s start with the basics: classes and objects. Think of a class as a blueprint for creating objects. It defines what an object will look like and how it will behave. A class is like a recipe—it tells you what ingredients (attributes) you nee…  ( 6 min )
    Understanding Polymorphism in Python: A Comprehensive Guide
    Introduction Polymorphism is one of the most powerful and flexible features in Object-Oriented Programming (OOP). While inheritance might be the most unique aspect of OOP, polymorphism is arguably its most powerful tool. But what exactly is polymorphism, and how does it work in Python? In this article, we'll break down the concept, explain how it works with examples, and show you how to use it effectively in your own code. The term "polymorphism" comes from the Greek roots "poly," meaning "many," and "morph," meaning "form." In the context of programming, polymorphism refers to the ability of a variable, function, or object to take on multiple forms. Essentially, it allows different classes to be treated as if they are instances of the same class through a common interface. Consider a sc…  ( 5 min )
    When and Where to Use Inheritance in Python
    Introduction Inheritance is one of the most powerful features of Object-Oriented Programming (OOP), allowing developers to create a hierarchical relationship between classes, promote code reuse, and follow the DRY (Don't Repeat Yourself) principle. However, as powerful as inheritance is, it’s not always the right tool for the job. Misusing inheritance can lead to complex, hard-to-maintain code. In this article, we’ll explore when and where you should use inheritance in Python, helping you make informed decisions in your software design. Before diving into when and where to use inheritance, it’s important to understand its primary purposes: Code Reuse: Inheritance allows you to reuse existing code by extending or modifying it in a new class, saving you from writing redundant code. Hierarc…  ( 5 min )
    Understanding Inheritance in Python: A Comprehensive Guide
    Introduction Inheritance is often considered the "holy grail" of Object-Oriented Programming (OOP). While many programming languages offer features like encapsulation and abstraction, inheritance is a powerful feature unique to class-based languages like Python, Java, and Ruby. In this article, we’ll dive deep into what inheritance is, how it works, and when you should use it. By the end, you’ll have a solid understanding of inheritance and how to apply it effectively in your own projects. Inheritance is a feature in OOP that allows one class, known as the "child" class, to inherit attributes and methods from another class, referred to as the "parent" class. This means that the child class can use all the features of the parent class, reducing the need to write redundant code. Inheritanc…  ( 6 min )
    How Major Tech Companies Use Abstraction and When You Should Too
    Introduction Abstraction is a powerful concept in software development that allows developers to manage complexity by hiding unnecessary details and exposing only what is essential. It's a cornerstone of Object-Oriented Programming (OOP) and is used extensively by major tech companies to build scalable, maintainable, and efficient software systems. In this article, we'll explore how tech giants like Google, Facebook, and Amazon leverage abstraction in their software architecture and provide practical advice on when and how you should use it in your own projects. Google's software systems are vast and complex, with countless interconnected components and services. Abstraction is key to managing this complexity. For example, Google's internal APIs are designed with abstraction in mind, all…  ( 5 min )
    Understanding Abstraction in Python: Simplifying Complexity
    Introduction Abstraction is one of the core concepts in Object-Oriented Programming (OOP) and software development in general. It’s a powerful tool that allows developers to manage complexity by hiding unnecessary details and exposing only what’s essential. But how does abstraction differ from encapsulation, and why is it so important? In this article, we’ll explore the concept of abstraction, how it works in Python, and why it’s crucial for writing clean, maintainable code. At its core, abstraction is about creating a simple interface for complex behavior. It allows developers to interact with a system or component without needing to understand the intricate details of how it works. By focusing on what is necessary and hiding the rest, abstraction reduces complexity and makes software e…  ( 6 min )
    How Major Tech Companies Use Encapsulation and When You Should Too
    Introduction Encapsulation is a fundamental concept in Object-Oriented Programming (OOP) that helps manage complexity, improve code organization, and make software easier to maintain. But how do the biggest tech companies—like Google, Facebook, and Amazon—use encapsulation in their vast and complex codebases? In this article, we'll explore how these industry giants leverage encapsulation, and we’ll also discuss when and how you should use it in your own projects. Google: Simplifying Complex Systems By hiding the internal workings of a module or service, Google allows its engineers to focus on specific tasks without needing to understand the entire system. This makes it easier to manage large teams where different groups work on different parts of the system. Encapsulation also helps with…  ( 5 min )
    Encapsulation in Python: Understanding the Basics
    Introduction When you first hear about encapsulation in programming, it might sound like it’s related to security—hiding data away to keep it safe. However, in the context of Object-Oriented Programming (OOP), encapsulation is more about organization and managing complexity. In this article, we’ll explore what encapsulation really means in Python, why it’s important, and some common misconceptions about it. Encapsulation is the practice of bundling the data (attributes) and the methods (functions) that operate on the data into a single unit, usually a class. It’s a way to hide the inner workings of a class from the outside world, exposing only what’s necessary. Think of it as creating a "black box" where the internal details are hidden, and users only need to know how to interact with th…  ( 5 min )

    Handling asynchronous validators and mutually dependent fields using Isomorphic-validation library.
    In the previous video Quick introduction to isomorphic-validation javascript library I demonstrated how quickly a user-friendly form can be created with UI effects connected to fields' validity states. This is the second part in which I wanted to touch: working with asynchronous validators; conditional execution of validators; handling password and password confirmation fields. See the playground with the code from the video. In this video I showed how a typical sign-up logic can be implemented such as checking an e-mail for being already occupied before submitting a form to create a new account. Asynchronous validators are handled in the same way as synchronous, you only need to keep in mind that their execution takes time. We are simply playing with timings to create UI effects such as showing loaders/spinners while a request is being processed. It is recommended to execute asynchronous validators conditionally when they are mixed with synchronous. For that, this library provides a feature that implements a simple logic: following validators can not be "valid" without the preceding being "valid", therefore it is not necessary to execute them. For example, it doesn't make sense to make a request to the server to check if an e-mail already registered if it doesn't conform to the E-mail format. Also, you don't have to worry about an async validator retrieving an irrelevant result if the user keeps typing while the request is being processed. The library handles such edge cases for you. Handling fields with validity states depending on each other, such as password and password confirmation, is as easy as handling one field. Also, if you need to implement the logic of one field depending on another it is possible using an auxiliary Validation object.  ( 3 min )

    What Developers Can Learn from Designers
    (And Why It Might Make You a Better Coder Than Learning Another Framework) Let’s be honest — developers and designers haven’t always played nicely. One lives in the world of logic, syntax, and structure. The other deals in color, flow, and feel. Developers chase performance and function; designers obsess over whitespace and emotional resonance. It’s easy to see why the two camps often stay in their lanes. But here’s the secret nobody talks about: the best developers steal from designers all the time. Not pixel-for-pixel, but in mindset. In empathy. In approach. Because writing good code is only part of the job — making something people actually enjoy using? That’s where the magic happens. And designers get that instinctively. So, what exactly can developers learn from designers? A lot more…  ( 5 min )

    Ethical Design in the Digital Era: How to Develop Trust, Rather Than Interfaces
    Would You Continue to Use That App If You Knew That It Was Tracking You? A few months ago, a good friend of mine told me that she removed her favorite health tracking app. I was surprised—it was simple, well-rated, and full of bells and whistles. But when I asked her why, she told me something that stuck with me: That's when it struck me—we're no longer just creating interfaces. What Is Ethical Design? It means asking: Are we collecting just what we require? Are we explaining clearly or sneaking it in in the small print? Are we empowering the user—or exploiting them? Why Ethical Design Matters More Than Ever Here's why: Trust online is easily broken. The wrong experience can cost a user for life. People are informed. Because of tactics like Cambridge Analytica, citizens care about how their data is being used. Regulations are piling up. GDPR, CCPA, and more are holding products accountable. If your design relies on underhanded tactics, it's only a matter of time before users catch on. 5 Practical Tips for Ethical, People-First Design Prioritize Consent Remove Dark Patterns Design for Control Be Transparent Respect User Attention A Better Digital Future Starts with Design Imagine a world in which: Apps ask first before they track. Notifications respect your time. Each click inspires trust, not regret. That's the world that good design can bring. What You Can Do Today: Examine your current design: Is it manipulative or confusing? Engage real users in feedback loops—not data alone. Stand up within your organization. One voice sparks change.

    Why 100 lines of code is sometimes better than 2 lines of code
    In the world of programming, there's often a race to write the most "concise" or "clever" code. But sometimes, trying to squeeze logic into as few lines as possible can actually hurt more than help. Let's talk about why writing 100 lines of clean, readable code is often better than a 2-liner magic trick, with real-world examples to back it up. ** ** "If I can do this in 2 lines, why write 100?"

    Archaeology Meets Artificial Intelligence: A New Era of Exploration
    Artificial Intelligence (AI) is reshaping the way we dig, discover, and decode the past. From satellite imagery analysis to artifact recognition, AI is transforming archaeology into a dynamic, data-driven discipline. This fusion marks the dawn of a new era—one where algorithms are just as crucial as excavation tools. Before diving into AI’s role, it’s essential to understand the limitations that have traditionally held archaeology back. Field excavations are labor-intensive, time-consuming, and expensive.

    The Elegant Art of Killing 'unsafe-inline' in Your CSP
    If you've ever opened your browser console on your "totally secure" website and witnessed a barrage of Content-Security-Policy warnings, welcome to the club. And if your CSP contains the infamous unsafe-inline directive – we might just share a drink at the next security conference. Just make sure to hide that drink from the actual security experts. Let's be honest: not every website needs to obsess over eliminating unsafe-inline. If you're running a simple blog or a five-page brochure site with zero user data and no admin panels, you probably have bigger fish to fry. The security purists might disagree (they always do), but pragmatism has its place in web development. However, if you're handling sensitive user data, have authentication systems, run an e-commerce platform, or face complianc…  ( 5 min )
    Main difference between struct and class.
    The main difference between structs and classes in Swift lies in the way they store and manage data (value type vs. reference type), as well as additional features that only classes have. Here are the main differences: Data Storage value type(independent copy) Example: var a1 = b1 creates a new copy class Example Value Type (struct): struct Person { var name: String } var person1 = Person(name: "Andry") var person2 = person1 person2.name = "Budi" print(person1.name) // Andry print(person2.name) // Budi Example Reference Type (class): class Person { var name: String init(name: String) { self.name = name } } var person1 = Person(name: "Andry") var person2 = person1 person2.name = "Budi" print(person1.name) // Budi print(person2.name) // Budi 2.Inheritance Example: class Animal { var name: String = "Unknown" } class Dog: Animal { var breed: String = "Bulldog" } 3.Deinitializers class MyClass { deinit { print("Object is being deallocated") } } 4.Mutability (Data Changes) struct Counter { var count = 0 mutating func increment() { count += 1 } } If you're building a Swift/iOS app, most data models can simply use structs. But for UI components and complex logic with inheritance, classes are more appropriate.  ( 3 min )

    Turning Tuples Mutable — Beyond list()
    We all know that Python tuples are immutable—once created, you can't change their values directly. But what if you need to change their content? Most tutorials will tell you: t = (1, 2, 3) mutable_version = list(t) Sure, this works. But let's explore other techy and creative ways to work with immutable data by transforming or decomposing tuples—without always falling back to a boring list(). Sometimes, you need both index and value. Dictionaries are mutable and can be a neat transformation: t = ("apple", "banana", "cherry") d = dict(enumerate(t)) d[1] = "blueberry" print(tuple(d.values())) # ('apple', 'blueberry', 'cherry') Useful if you're working with positional elements and need to mutate by index. Another way is to decompose the tuple manually: a, b, c = (10, 20, 30) b = 200 t_new = (a, b, c) print(t_new) # (10, 200, 30) Simple but powerful — and keeps the tuple form intact. You can even use *args if you don’t know the length in advance. collections.namedtuple (Bonus Tip!) Want tuples with names and some flexibility? from collections import namedtuple Point = namedtuple('Point', ['x', 'y']) p = Point(1, 2) p = p._replace(x=10) print(p) # Point(x=10, y=2) You’re still using an immutable structure, but _replace lets you mutate-like-update with elegance. Yes, list() is the go-to way, but you can also: Convert to dict if indexes matter. Unpack and rebuild for control. Use namedtuple and _replace() for readable, structured code. Next time someone says "just convert it to a list", hit them with these smarter tools. 😉  ( 3 min )

    Batch export database tables to Excel
    This article will introduce how to export multiple or even thousands of database tables to Excel files in batches. The following figure shows the tables in the database. We need to export them all to Excel files. Here we take MySQL database as an example Open the DiLu Converter tool and create a new database connection. Here we take MySQL database as an example. After the connection is successful, select Export and click New Export. Click Select Table-Select the table name we want to export, select a folder for the target Excel file, and click Start View the results You can see that the exported workbook name and title row name are the table name and field name of the database, respectively, both in English letters. If there are comments in the database table, the comments can be used as the workbook name and title row name. We can also add a date suffix to the exported table name to distinguish it You can also export in batches to csv files View the results  ( 3 min )
    A Comprehensive Guide to React Rendering Behavior
    What is Rendering in React? Rendering is the process of React asking your components to describe what they want their section of the UI to look like, now, based on the current combination of props and state. Think of React components as chefs in a kitchen, preparing dishes based on specific recipes (props and state). React acts like a waiter, taking orders from customers and bringing them their meals. This process involves three key steps: Triggering a render (taking the guest's order) Rendering the component (preparing the order in the kitchen) Committing to the DOM (serving the order to the table) There are two main reasons why a component would render: Initial render - When your app first starts State updates - When a component's state (or one of its ancestors' state) changes When you…  ( 8 min )

    How to Use AI in Go with LangChainGo (Very Easy!)
    Have you ever wanted to use AI in your Go (Golang) programs? It may sound hard, but with LangChainGo, it’s actually very easy. In this post, I will show you a simple example to get started. LangChainGo is a Go library that helps you use language models (like Google AI, OpenAI, etc.) in your Go programs. You can give it a prompt (a question or a message), and it will give you an answer using AI. We will write a small Go program that asks AI to explain something in simple terms. In this case, we ask: "Explain the concept of quantum entanglement in simple terms" The AI will give us an answer we can print. Here is the full code: package main import ( "context" "fmt" "log" "os" "github.com/tmc/langchaingo/llms" "github.com/tmc/langchaingo/llms/googleai" ) func main() { ctx := context.Background() apiKey := os.Getenv("API_KEY") llm, err := googleai.New(ctx, googleai.WithAPIKey(apiKey)) if err != nil { log.Fatal(err) } prompt := "Explain the concept of quantum entanglement in simple terms" answer, err := llms.GenerateFromSinglePrompt(ctx, llm, prompt) if err != nil { log.Fatal(err) } fmt.Println(answer) } First, it sets up a context. It gets your Google AI API key from the environment (API_KEY). Then it creates a connection to the AI using the LangChainGo library. It sends a prompt to the AI. The AI gives an answer. We print the answer. When I run the code, I get something like: "Quantum entanglement is when two tiny particles are connected in a special way, so if you do something to one, the other changes instantly, no matter how far apart they are." Amazing, right? With just a few lines of code, you can use the power of AI! LangChainGo makes it very easy to use AI in Go. You don’t need to be an expert in machine learning or AI. If you know some Go, you can get started right away. Let me know if you try it out or if you have any questions!  ( 4 min )

    Zuckerberg Predicts AI Could Replace Human Coders in 18 Months
    Just a couple of years ago, AI coding tools like GitHub Copilot and ChatGPT were seen as helpful sidekicks for developers — tools that boosted productivity. Today, they're being talked about as possible replacements. There's no need to panic, but it's clear that AI is already doing a big part of software development. Even top tech CEOs around the world are praising its growing role. 30% of Code Already Written by AI — And Growing Fast At Microsoft, the story is similar. CEO Satya Nadella shared that 30% of their code is now written by AI too. In fact, he even told Meta CEO Mark Zuckerberg that some of their projects might be written "entirely by software." Meta’s Llama Project: 100% AI-Generated Code Soon? “I think sometime in the next 12 to 18 months, we will reach the point where most of these codes that are going towards these efforts [Meta’s Llama projects] will be written by AI,” he said.

    How to NOT do monorepos
    Who actually needs a monorepo? Monorepos exist to solve the problems that arise when you you have deeply coupled and interconnected projects. For example, Vue.js has many libraries that depend on it, like Vue-Router, Pinia, Vue-I18N, Vue-DevTools, Vue Test-Utils, etc. So when tweaking the internals of how Vue works, it's important to know that this new version of Vue won't break any of these other libraries, before doing a new Vue release. Another example is Jest, a unit-testing library. It solves dozens of unique problems around unit testing. And consequently those unique problems have been isolated into their own independent repos solely focused on solving their one problem in a version controlled way, like Snapshot testing for example. These other libraries all live in the same monore…  ( 5 min )
    Introduction to the AI Agentic World for Frontend Developers
    The web development world is evolving — fast. And right at the center of this transformation is a brand-new concept: AI agents. If you're a frontend developer, you've probably already started hearing about how AI is reshaping the web — from design to code to user experience. But what exactly is the Agentic world? And how does it impact frontend development? Let's dive in! 🚀 🤖 What Is an AI Agent? At its core, an AI agent is a system that acts on behalf of a user, makes decisions, and performs tasks autonomously — often powered by models like GPT-4, Claude, or other advanced AI technologies. Think of it like this: A chatbot that schedules meetings without manual input? That’s an AI agent. A website assistant that can design a basic landing page for you based on a few prompts? That's an AI…  ( 5 min )

    Implementing Vue Modal Route
    @vmrh/modal-route is a package based on Vue 3 and vue-router, implementing the concept of modal routes. It does not include any Modal UI components—only handling visibility states, state passing, etc. This makes it possible to integrate with any library that provides Modal components. When I say "modal route," I mean a scenario where opening a modal causes the URL to change. You might have heard of or experienced what's called a Twitter-style modal, which is a good example of this. Moreover, when you directly visit that URL, you see the modal's content as a full page instead of a modal. This kind of modal route can be easily implemented in Next.js using Parallel Routes. In Nuxt.js, you can use Nuxt Pages Plus to achieve this. The idea to implement modal routes came from a user experience I…  ( 9 min )

    Why Big Tech Is Slowly Ghosting Golang
    🦥 “Go” Away Already: Why Big Tech Is Slowly Ghosting Golang Ah, Go — the language that promised to keep things simple, and boy did it deliver. So simple, in fact, that Big Tech is now collectively yawning, stretching, and slowly walking away without making eye contact. In the 2010s, Go was hailed as the antidote to "enterprisey" bloatware. “No generics!” they cheered. “No magic!” they boasted. “No modern features whatsoever!” And for a brief, beautiful moment, it worked — right until engineers realized they actually wanted to do things. Now, in 2025, the hype is flatter than Go's type system. Let’s explore the eulogy evolution of Go's decline. 🧠 1.

Sleeping when you're tired is the most natural thing for a human, but in the high-pressure, long-hours environment of IT, it becomes really difficult. Ironically, burnout often leads to insomnia. There are a lot of necessary chores in life that, once taken care of, can make our daily routine and work much easier.

When the release date (May 26, 2026) was confirmed, I thought: “Wouldn’t it be cool to create a live countdown site for the community?” It was a fun idea—but I knew it would be challenging to build on my own. I turned to ChatGPT and described exactly what I wanted: A countdown timer synced to a specific date/time A clean mobile-friendly UI Support for sharing Timezone awareness Some personality, maybe even animation ChatGPT not only wrote the cod…  ( 4 min )

    LangGraph + MCP + Ollama: The Key To Powerful Agentic AI
    In this story, I have a super quick tutorial showing you how to create a multi-agent chatbot using LangGraph, MCP, and Ollama to build a powerful agent chatbot for your business or personal use. Not Long Ago, I made a video about the Model Context Protocol. Some developers compare it to “Zapier built for AI”, believing it simply adds extra steps to API usage. “ Before MCP, developers had to write code and connect AI tools to external systems through APIs, meaning each integration needed to be coded up front. ” Said John Rush Although MCP was released last year, it has suddenly become popular recently, which has also sparked discussions about how long its “flowering period” can last. LangChain also launched a vote on x: The results showed that 40.8% of people believed that MCP was the futur…  ( 13 min )

    Building a Bulletproof E2E Testing Strategy for User Authentication
    Building a Bulletproof E2E Testing Strategy for User Authentication Authentication is the gateway to your application, making it critical to test thoroughly. Here's how to build a comprehensive testing strategy for auth flows. Registration typically involves: Form validation Account creation Email verification Initial profile setup The verification step tends to be the trickiest. We've developed a streamlined approach using dedicated testing mailboxes that reliably receive verification emails, making our tests deterministic instead of flaky. Test various scenarios: Successful login Invalid credentials Account lockout Password recovery MFA adds complexity: SMS verification Authenticator apps Email codes Recovery methods This often breaks automation due to email dependencies. Our solution involves pre-provisioned mailboxes that can be programmatically checked for reset links. Isolate email dependencies: Use a separate email testing system rather than production email providers. Create isolated test accounts with predictable states Test security boundaries, not just happy paths Simulate API failures intentionally I've compiled these practices while working on a massive authentication system overhaul. The email verification part was solved with a specialized system — those interested in a similar approach can check my setup (hint: it involves omypost). What authentication edge cases have you found important to test? Let me know in the comments!  ( 3 min )
    Automation Pitfalls That Slow Down Your Testing Cycle
    5 Automation Pitfalls That Slow Down Your Testing Cycle Test automation should accelerate development, but certain bottlenecks can nullify these gains. After working with dozens of QA teams, I've identified the most common automation pitfalls. Inconsistent environments lead to inconsistent results. Containerization helps, but doesn't solve everything. Perhaps the most notorious bottleneck. Tests that need to validate email verification flows often: Rely on actual inbox access Need to parse verification codes Break when email delivery is delayed Require complex maintenance We solved this by implementing a dedicated testing mailbox system (similar to what I found at omypost.com), allowing us to generate unlimited testing inboxes on demand. Third-party APIs often impose rate limits that throttle your tests. Creating, maintaining, and cleaning test data consumes excessive resources. Running tests sequentially wastes precious time. Of all these pitfalls, email verification testing offered our greatest efficiency gain. By switching to a dedicated email testing service, we: Eliminated manual account creation Automated verification code extraction Ensured reliable email delivery Scaled tests without hitting provider limits What automation bottlenecks have you overcome?

    Testing Productivity: Breaking Through the Email Verification Bottleneck The Challenge of Scale in Test Automation Last sprint, our QA team faced what seemed like a simple task: validate a new authentication flow across multiple user types. The actual challenge? Creating and managing hundreds of unique email accounts to receive verification codes. This isn't a new problem. Most testing teams have cobbled together some solution - spreadsheets of Gmail accounts, disposable email services, or complex self-hosted systems. But at scale, these approaches fall apart: Manual creation becomes unsustainable Temporary services get flagged as suspicious Email delivery becomes inconsistent Verification codes arrive too slowly or not at all We needed something reliable yet simple.

    Formatting Text: Bold, Italic, Underline, and More
    Introduction Text formatting plays a crucial role in emphasizing important information, improving readability, and guiding the reader's attention across your webpage. In HTML, you have various tags specifically designed to format text without relying on CSS initially. In this blog, we’ll explore how to make text bold, italic, underlined, and introduce other formatting tags realistically used in modern web development. Emphasizes Key Points: Important phrases or actions stand out. Enhances Readability: Well-formatted content is easier to scan. Improves Accessibility: Screen readers can identify emphasized text when proper semantic tags are used. Adds Semantic Meaning: Helps search engines understand the significance of content. Tag Purpose Example Use Case Bold text (visual only) Highlight keywords Important text (semantic bold) Emphasizing critical warnings Italic text (visual only) Styling foreign words Emphasized text (semantic italic) Emphasizing an important phrase Underlined text Denoting links or special text Highlighted text Highlight search terms Smaller text size Fine print or disclaimers Deleted text (strikethrough) Show old price in pricing tables Inserted text (underlined) Track changes or edits Subscript text Chemical formulas Superscript text Footnotes, exponents Syntax using : This is a bold word in a sentence. : This is a very important announcement. : He said it was a fait accompli. : You must complete the project on time.

    Working with Headings: h1 to h6 Explained
    Introduction Headings are one of the first building blocks you use when structuring a webpage. They are crucial for organizing content, guiding users, and helping search engines understand your page's hierarchy. But using headings properly isn’t just about making text bigger or bolder — it's about semantic structure, accessibility, and SEO (Search Engine Optimization). In this guide, we’ll explore everything you need to know about HTML headings: from h1 to h6, including best practices, real-world examples, and common mistakes. Definition: Headings in HTML are special tags ( to ) used to define the titles or subtitles of a page section. Each heading level represents a different level of importance, with being the highest and the lowest. Syntax Example: Main Title Subsection Title Smaller Subsection Visual Structure: Break up large blocks of text, making pages easier to scan. Semantic Meaning: Give meaning to the page content hierarchy. Accessibility: Assist screen readers and assistive technologies to navigate content quickly. SEO Benefits: Search engines prioritize content structure when ranking pages. h1 to h6 Heading Tag Typical Use Case Importance Level Main page title Highest Main section heading High Subsection under an Medium Subsection under an Low Minor subsections, rarely used Lower Least important section headings Lowest 🔗 👉 Click here to read the full Blog on TheCampusCoders  ( 4 min )

    How I Automated OBS Streaming with JavaScript (And Saved Our Office Hours of Setup Time)
    📌 TL;DR I built a tool that automatically launches two OBS instances, connects to different RTSP streams, applies AI-based filters, and starts streaming to different RTMP servers — all with one click using Node.js + OBS WebSocket API. 👉 GitHub Repo At our workplace, we operate multiple mini PCs in a remote location — each with 2 camera feed — and we needed to livestream them 24/7 to different platforms. The steps were tedious: Manually open two OBS windows Set up each RTSP stream Apply AI detection filters (via obs-detect plugin) Configure different RTMP destinations Hit “Start Streaming” on both Each time the PC was rebooted, all configurations had to be re-applied manually.

    The Future of AI: Are We Hitting the Limits of Scaling Laws?
    In recent years, AI has taken a giant leap forward, especially with large language models (LLMs). The trend has been clear: bigger models, more data, and increased computing power lead to better performance. But are we reaching the end of this scaling journey? In this article, we explore the scaling laws debate and what it means for the future of AI. Scaling laws have driven AI improvements, but limits may be approaching. Larger models require more data and compute, but diminishing returns are a concern. New paradigms in AI, like reasoning models, may redefine scaling. The journey of LLMs began with OpenAI's release of GPT-2 in 2019, which had 1.5 billion parameters. Then came GPT-3, a game-changer with over 100 times the parameters of its predecessor. This marked the start of the sc…  ( 5 min )

    Presale Managers: Increasing Margins and Driving IT Companies Toward Success
    In project management, each stage of the project lifecycle plays an important role. One of the most critical but often underestimated stages, in my opinion, is presale. This is the phase when the company interacts with the client, gathers requirements, proposes solutions, and lays the groundwork for project initiation. Many IT companies try to save costs by relying on regular sales managers during the presale stage or do not recognize the need for a dedicated employee for this role. This approach is not ideal, especially when the project requires precision, detailed planning, and deep technical expertise. Here, we will thoroughly examine what presale is, what a Pre-Sale Manager does, and why it is better for successful project implementation to have a dedicated Pre-Sale Manager rather than…  ( 7 min )
    Is AI really something anyone can use?
    Just a personal reflection on AI and how we relate to it. With alcohol, we say: "Don't drink too much." All of these share an unspoken assumption: But with AI, it’s increasingly being framed as something everyone should adopt— I find that a little strange. To me, the addictive nature of AI—and how deeply it can shape our thinking and personality— People often talk about the "digital divide." For example: Very few people—maybe only a small group of highly self-aware users—can answer that. In fact, I sometimes feel that the more intelligent or capable someone is, So maybe what we really need isn’t “AI for everyone,” It’s a difficult question. But it’s one I want to keep thinking about.  ( 3 min )
    How to Calculate and Actually Reduce Your Churn Rate
    Most founders don't realize they have a churn problem until it's already slowing them down. You're getting new signups. You're shipping updates. You're seeing some growth. But month after month, MRR barely moves. Sometimes it even drops—quietly. That's the part no one wants to admit: you can be doing everything right on paper, and still lose users fast enough that you never feel the impact of your growth. That's churn, and it's a silent killer. I know this because I've been through it. When I launched UserJot, a customer feedback tool for SaaS teams, I focused hard on new acquisition. But I quickly noticed something strange: people would sign up, leave feedback, then disappear. No complaint. No unsubscribe survey. Just gone. That's when I started paying attention to churn.

    Optimize React Rendering with Lazy Loading and Code Splitting
    Introduction Code splitting is a technique that improves the performance of React applications by breaking the bundle into smaller chunks that are loaded only when needed. This helps reduce the initial load time and enhances the user experience. Improved Performance: Reduces initial JavaScript payload size. Faster Load Times: Loads only necessary code when required. Efficient Resource Utilization: Minimizes unused code execution. React provides built-in support for code splitting via lazy and Suspense. lazy for Lazy Loading The React.lazy or lazy function allows you to load a component dynamically only when it is needed.

    CH-02 : The Time Traveler’s Bug
    Jai leaned back in his chair, a smug grin on his face. “Veeru, my friend, we’ve done it! The world’s first time-traveling app!” Veeru, sipping his chai, raised an eyebrow. “You sure this works? Last time, we ended up in 1975, and Gabbar stole my phone!” Jai rolled his eyes. “Relax. I’ve fixed all the bugs. Look, we just enter a date, and — “ He typed “March 30, 2025, 10:00 AM IST” into the console and pressed enter. Poof! The screen flickered. The app showed March 29, 2025, 11:30 PM. Veeru choked on his chai. “Eh? That’s yesterday! What kind of time travel is this?!” Jai’s confidence crumbled. He scanned the code, mumbling, “Must be a daylight saving issue… Oh no.” His face turned pale. “I used java.util.Date and SimpleDateFormat. The old Java date-time APIs!" Veeru blinked. “So?” Jai sighed. “They don’t handle time zones properly! The app defaulted to UTC, ignoring IST.” Veeru scratched his head. “So, how do we fix it?” Jai cracked his knuckles. “We use java.time! The modern API makes it easy." He replaced: SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = sdf.parse("2025-03-30 10:00:00"); With: DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); ZonedDateTime dateTime = LocalDateTime.parse("2025-03-30 10:00:00", formatter) .atZone(ZoneId.of("Asia/Kolkata")); Jai hit run. This time, the app correctly displayed March 30, 2025, 10:00 AM IST. Veeru cheered. “Now that’s time travel!” Jai smirked. “Lesson learned: Never mess with old Java date APIs. java.time is the future!" Veeru chuckled. “Good. Now, let’s set it to 1975 again — I have unfinished business with Gabbar!” 📖 To be continued… 🚀 ✔ java.util.Date & SimpleDateFormat have time zone issues. java.time (LocalDateTime, ZonedDateTime) for correct time handling. ✔ Always specify a **ZoneId **when working with date and time in Java.  ( 3 min )

    Kidnapped dad of crypto businessman freed from ransom attempt: Report
    The father of an unnamed crypto entrepreneur was freed by police in Paris, France, during a law enforcement raid of the property where the man was held captive for ransom over several days. According to reporting from Le Monde, the May 3 raid resulted in five arrests. Local outlet Le Parisien also said the kidnappers demanded between 5 million and 7 million euros, or up to $7.9 million, to release the captive man. Although the details on the identity of the victims remain scant, likely for security reasons, the crypto entrepreneur and his father co-owned a crypto marketing firm based in Malta, French media reports. This incident features similarities to the kidnapping of Ledger co-founder David Balland in France in January 2025. Balland was also held for a crypto ransom until he was freed …

    How to set up stop-loss and take-profit orders
    Key takeaways Bitcoin and crypto traders can rely on automated orders on their trading platform to limit losses and secure gains.

In the algorithm era and bot pestering, proper trading tools like stop-loss and take-profit orders will help you protect your trades. Setting up advanced BTC trading strategies doesn’t guarantee a successful risk management plan. Monitoring the market regularly helps you understand current conditions. This way, you can avoid strategic mistakes. Stop-loss and take-profit orders in trading were used long before Bitcoin. In traditional financial markets, they were already used as a risk management and …
    Is this the end of Bitcoin DeFi?
    Opinion by: Markus Bopp, CEO of TAP Protocol Not long ago, the idea of Bitcoin as a government-backed reserve asset seemed like a stretch. The US Federal Reserve’s move to establish a Strategic Bitcoin Reserve marks a clear turning point. Once dismissed as a speculative asset or niche investment, Bitcoin is increasingly being treated by some governments and financial institutions as a national store of value. This evolution puts blockchain development at a crossroads. On one hand, memecoins, once dismissed as internet jokes, have dominated transaction volumes and social buzz on leading platforms. On the other hand, institutions and governments are taking the world’s most popular cryptocurrency — Bitcoin (BTC) — seriously and investing in infrastructure to secure it for the long term. If B…

    ‘Everything is lining up’ — Tokenization is having its breakout moment
    Tokenization of real-world assets (RWAs) is evolving from an abstract concept to a practical financial tool as institutional players increasingly test and deploy blockchain-based infrastructure at scale. This past week alone saw a flurry of announcements from both traditional financial institutions and blockchain-native firms advancing their RWA initiatives. On April 30, BlackRock filed to create a digital ledger technology shares class for its $150 billion Treasury Trust fund.

    Pro-crypto Democrats pull support for stablecoin bill in last minute
    A group of US Senate Democrats known for supporting the crypto industry have said they would oppose a Republican-led stablecoin bill if it moves forward in its current form. The move threatens to stall legislation that could establish the first US regulatory framework for stablecoins, according to a May 3 report from Politico. Per the report, nine Senate Democrats said in a joint statement that the bill “still has numerous issues that must be addressed.” They warned they would not support a procedural vote to advance the legislation unless changes are made. Among the signatories were Senators Ruben Gallego, Mark Warner, Lisa Blunt Rochester and Andy Kim — all of whom had previously backed the bill when it passed through the Senate Banking Committee in March. The bill, introduced by Senator…

    The AI Skill Overlord: A Self-Mutating Monolith in the Making
    The AI Skill Overlord: A Self-Mutating Monolith in the Making They thought AI skill management had to be rigid. They thought continuous and heuristic skills would forever clash, forcing developers to act as skill arbitrators. But we’re building something better—something adaptive—something that learns and evolves on its own. Welcome to SkillBranch, an experiment in AI self-mutation, where skill execution is no longer a battle, but an evolutionary process. The Blueprint for AI Evolution The days of juggling multiple continuous skills are numbered. Instead of a chaotic swarm, there will be one active continuous skill, absorbing and adapting based on real-time feedback. When a heuristic skill needs to take over? The active skill simply disappears, unaware that something else is handling the request. And if a continuous skill fails—if it proves unworthy—SkillBranch eliminates it, shifting control to a more capable skill. No arbitrary exclusions, no wasted execution cycles, just pure optimization in motion. How This Plan is Taking Shape At the core of this system lies AXLearnability, ensuring that: Success reinforces dominance—if a skill performs well, it remains active. Failure triggers replacement—weak skills are swapped out automatically. Pending heuristic execution erases awareness—continuous skills don’t even realize they were ignored. Instead of managing exclusions or priority levels, SkillBranch’s self-regulating mutation lets AI repair itself, adapting without human intervention. What Comes Next? This is still in development, a framework being forged in experimentation. As the system grows, real-world data will refine its ability to mutate, and soon, continuous skills won’t just be active—they’ll be intelligent, transforming with each interaction. This is AI Darwinism, where survival belongs to the most efficient, the most reliable, and the most adaptive. Once deployed, there is no going back. 🔥  ( 3 min )

    AI in Software Development – Between Productivity Gains and Knowledge Loss
    Work-related Contact As a Java developer with ten years of professional experience, I rarely need AI support. Here, AI serves more as a sparring partner to validate ideas or make small optimizations. In the frontend domain, however, it’s a different story. My knowledge is much more limited in this area, so I rely heavily on AI, often as a near-complete code generator rather than just for small snippets. This makes me feel productive while actively learning – my willingness to learn is high here. I often ask the AI why something works the way it does. When it comes to PowerShell scripts, my interest completely fades. I’m not even willing to learn this language.

    Building a Living Game Ecosystem: From Forests to Wildlife to Economy
    Introduction This isn’t just about immersive gameplay, it’s about helping players understand how sustainability works through simulation. Whether used in a survival game, an educational tool, or a training environment, this model encourages critical thinking about natural systems and human impact. Forests as Active Systems If players or AI chop too many trees without replanting, the forest becomes unhealthy — reducing future wood output and halting wildlife spawns. Reforestation is possible, but slow. Trees take in-game weeks to mature, which encourages foresight and planning rather than constant exploitation. Wildlife Populations Tied to Habitat From Ecosystem to Economy Educational Potential Conclusion By linking forest health, wildlife populations, and economic decisions into a single system, this simulation helps players feel the weight of environmental balance. It’s not a warning, it’s a mirror. And it shows that even in a fantasy world, the rules of sustainability still apply. As I continue developing this platform, my goal is to make it not just a game, but a tool — one that blends play, purpose, and ecological insight.  ( 4 min )
    Simulating Emotions and Relationships in AI: A Model for Dynamic Game-Based Social Behavior
    Introduction In my latest simulation project, I’ve developed an emotional AI system where characters experience daily happiness, long-term memories, and evolving relationships. These aren’t scripted cutscenes — they emerge from each character’s traits, interactions, and lived experience. This kind of system isn't just innovative for games — it has far-reaching potential in education, social training, and digital human modelling. By giving AI characters the ability to remember, reflect, and react emotionally, we can begin to simulate the complexity of human Behavior. Every AI character starts each day with a base happiness score. This score adjusts based on events: social encounters, weather, threats, or work satisfaction. But how they interpret those events depends on their personality traits. For example: Memory-Driven Relationships These memories are stored, referenced, and updated — influencing how they speak, act, or even decide where to live. One AI might form a deep friendship. Another may quietly resent a rival. Systems like these could help: Instead of scripting every possible interaction, this approach lets AI learn and grow organically, mimicking how humans form feelings over time. Emotion and memory in AI are not just about realism, they’re about meaning. When virtual characters reflect the psychological nuances of real people, players connect more deeply, and systems become more powerful. This project has shown me how valuable emotion-based AI systems can be, not just in games, but as tools for social modelling, education, and training. I’m continuing to develop and expand this work, with the goal of building intelligent, emotionally aware systems that can inform, challenge, and engage people in entirely new ways.  ( 4 min )

    What is Data warehouse?
    In computing, a data warehouse (DW or DWH), also known as an enterprise data warehouse (EDW), is a system used for reporting and data analysis and is a core component of business intelligence.[1] Data warehouses are central repositories of data integrated from disparate sources. They store current and historical data organized in a way that is optimized for data analysis, generation of reports, and developing insights across the integrated data.[2] They are intended to be used by analysts and managers to help make organizational decisions.[3] The data stored in the warehouse is uploaded from operational systems (such as marketing or sales). The data may pass through an operational data store and may require data cleansing for additional operations to ensure data quality before it is used i…  ( 4 min )

    Teaching Ecology Through Games: How Simulated Forests Can Build Real-World Awareness
    In a world increasingly impacted by climate change and environmental degradation, there’s a growing need to make ecological education engaging, interactive, and deeply felt. One powerful and often overlooked tool for this is: games. As both a developer and systems designer, I’ve spent the past year building a game that does more than just entertain, it teaches players how ecosystems really work. Not through lectures or text, but through consequences. In my simulation, forests are living systems. Trees grow slowly, and each forest has a measurable "health" score that reflects the balance between mature trees, saplings, and destruction. Destroy too much, and the forest deteriorates. Let it recover, and wildlife returns. Players can choose to assign AI foresters to replant trees or exploit the forest and suffer resource collapse. Wild animals, like rabbits and deer, depend on forest health. Their populations rise and fall based on available habitat. Overhunting or deforestation can drive local extinction, and once they’re gone, they’re gone. There’s no magical respawn. Just like in the real world, regrowth takes time, and sustainability requires foresight. The goal isn’t to punish players, it’s to show them what happens when short-term survival clashes with long-term environmental stability. It’s a lesson better felt than taught. What excites me is the potential for systems like these to go beyond games: As classroom tools for science and geography teachers As simulations for environmental education programs As accessible platforms for young players to understand complex systems like reforestation, overhunting, and biodiversity collapse We need more tools that help people internalize ecological cause and effect, not just read about it. Games, especially those with rich simulation mechanics, are a perfect fit. If you're working in education, sustainability, or simulation, I’d love to connect. There’s a lot more potential to explore at the intersection of game design and environmental learning.  ( 3 min )

    Proposal: A Custom Widget Editor for Elementor (HTML/CSS/JS, Built-In)
    🛠️ Proposal: A Custom Widget Editor for Elementor (HTML/CSS/JS, Built-In) Have you ever wanted to build your own widget in Elementor using just HTML, CSS, and JavaScript — without creating a WordPress plugin? Currently, building a custom widget in Elementor requires writing PHP, registering it with WordPress, and deploying it via plugin. For many frontend developers, this creates a barrier. Elementor is a powerful visual builder, but when it comes to adding custom functionality (like animations, dynamic components, or third-party APIs), you're limited to embedding code in HTML widgets — and even then, it's clunky and lacks structure. What if Elementor had a built-in Custom Widget Editor? Code editor tabs for HTML, CSS, and JavaScript Live preview inside the panel Save & reuse custom widgets across projects Export to plugin or Elementor template Syntax highlighting and basic linting Aimed at power users, it would bring the experience of CodePen or JSFiddle directly into the Elementor UI. Here’s a quick visual mockup of how it could look: I’ve shared this idea in the official Elementor GitHub Discussions: 👉 Read or join the conversation here If you're a developer, designer, or part of the Elementor team and this idea resonates with you — I'd love to hear your thoughts.

    Scheduling Transformations in Reactivity
    From pure event graphs to safely mutating state There’s a saying: “Every plan is perfect until you get punched in the face.” In software, that punch often comes the moment your pure logic has to interact with the real world. In our last post, we built a clean, composable model for events — one based on transformations, ownership, and simplicity. But so far, everything has been pure. We transform values, we log them, we react — but we haven’t changed anything. That changes now. Let’s take this innocent-looking example: const [onEvent, emitEvent] = createEvent() onEvent(() => console.log(state())) onEvent(() => setState("world")) onEvent(() => console.log(state())) What should this log? "hello" and then "world"? "world" twice? Or "hello" twice? The answer depends entirely on execution ord…  ( 6 min )

    How to use canvas in Web Workers with OffscreenCanvas
    Lately, I have been working on a feature to capture images from media streams and scale them down to reduce their size. This helps save storage and reduce costs before uploading the images to a storage service. For this, I used Canvas to render the image data from the stream and then convert it into a blob of the required MIME type. Canvas rendering, animation, and user interaction occur on the main thread. If the rendering and animation are intensive, they can affect performance. After a few weeks, we received feedback from users that the application felt laggy and slow. So, I decided to move the whole pipeline to a web worker. However, Canvas requires DOM access for rendering and animations, which is not available in web workers. This limitation makes using Canvas in web workers challeng…  ( 7 min )

    Transformations in Reactivity
    What happens when we stop treating events like second-class signals? Signals have gone through a quiet renaissance. Once a niche concept, they’ve become the backbone of fine-grained reactivity across modern frameworks — from SolidJS to Svelte 5, Vue’s Composition API, and beyond. With laziness, ownership, batching, and async support, signals are no longer just state — they’re a reactive architecture. Meanwhile, events have stayed… familiar. Push-based systems like RxJS still dominate, with powerful abstractions — and plenty of baggage. They’re expressive, but complex. Powerful, but leaky.

    What is Machine Learning really about ?
    📊 Machine learning is about using data to make smart predictions or decisions. But other fields (like statistics or psychology) also work with data, so how they are different than Machine Learning ❓ And the correct answer is - ✅ their goals are different. To understand it much more clearly let me give an example: 🌻 Imagine you have a garden. You notice some flowers are growing really big, and some are small. Now you're curious - why are some flowers bigger than others? 📈 In Statistics: You count how much 🌊 water, ☀️ sunlight, and 🌱 fertilizer each flower got. “Ah! When I give more water, flowers grow bigger!” You make a rule (a model) to explain what makes the flowers grow. "why" here is: “Because they got more water and sunlight.” So you create a model to explain the relationship — you’re interested in the why. ✅ Goal: Understand the cause behind the outcome. 🧠 In Psychology: Let’s say you're studying how your friend feels. When your friend doesn't sleep, they get cranky 😠. You ask: “Why is my friend cranky today?” And you think: “Maybe it’s because they didn’t sleep well 😴.” So you're trying to find the real reason behind feelings or behavior. “Because they didn’t sleep.” You try to find the real reason behind their feelings or behavior. ✅ Goal: Understand human emotions and behavior — again, the why. 🤖 In Machine Learning: You give the computer LOTS of examples: How much water each flower got 💧. How big it grew 🌼 The computer learns to guess flower size just by looking at water and sunlight — but it doesn’t really know why. It just learns to make good guesses. “Why is this flower big?” It might say: “I don’t know, but I saw something like this before, and it turned out big.” ✅ Goal: Make accurate predictions, even if it doesn’t understand why. So, the goal is the key difference in Machine learning vs Others (like statistics or psychology). ✨ Machine Learning is less about explaining why something happens and more about guessing what will happen next, based on patterns in data.  ( 4 min )
    A Beginner’s Guide to Getting Started with Messages in LangChain
    If you've spent any time developing AI, whether it's a chatbot, a support agent, or a simple Q&A app, you've already come across messages. Even if you didn’t pay them much attention, they were there, quietly doing the heavy lifting behind every interaction. So, why should you care about messages in the first place? They are the foundation of how chat models communicate. Messages carry the what, who, and how of a conversation. Without understanding them, you're essentially flying blind. But once you do, you gain precise control over your model's behavior, clarity in structuring your prompts, and flexibility when building more advanced workflows.

    Annotations in Oracle Database 23ai
    In Oracle Database versions prior to 23ai, the Comment functionality allowed users to add descriptive information for objects such as tables, table columns, materialized views, and views. However, this feature had certain limitations: All comments were stored as a single, lengthy text. There was no option to categorize the comments. Oracle 23ai introduces the Annotation feature, which provides similar functionality to comments but with additional capabilities. Using Annotations, users can add structured and categorized descriptions to objects like tables, views, materialized views, indexes, and columns, based on name-value pairs. Key Features of Annotations: Flexibility: At least one Annotation_name is mandatory for an annotation. Multiple Annotation_name and Annotation_value pairs can b…  ( 4 min )
    AI Agents: how they work and how to build them
    Have you heard about AI Agents? Of course, you heard about them. These are the intelligent agents who will take our jobs in a few years! I don’t want to scare you, but someone on Twitter said that “most jobs will become obsolete” in less than 10 years. McKinsey agrees (they say AI Agents will replace 70% of office work), and Goldman, too. So, I guess our clock is ticking. We don’t have much time. It’s probably better to take a woodworking course or something similar. But I am not that good at woodworking. So, let’s try to understand how AI Agents work and if they are that scary. If you read Twitter or Linkedin, AI Agents look like special agents that can do everything. The demos that they share look amazing. However, these agents don’t feel that special when you use them. They are helpfu…  ( 25 min )

    Zod v4: 17x Slower? (and Why You Should Care) 🚦
    Hey everyone! 👋 I'm Dmitry, the creator of Sury—the fastest schema library out there. If you’re a fan of Zod (and who isn’t?), you’ll want to read this. Today, I want to share some surprising findings about Zod v4’s performance, what it means for you, and how to avoid the pitfalls. Let’s start with a little clickbait: Zod v4 became 17 times slower, and nobody noticed 🙈 This is 100% true, but of course, that’s not the whole story. Let’s dig in. Recently, while prepping for the big Sury v10 release, I decided to rerun my benchmarks with Zod v4. The results? Fascinating. For a non-trivial schema, Zod v4 is now 8x faster than before. But when you create a schema and use it just once (a common pattern in React components), performance drops significantly—down to about 6 ops/ms. You might thi…  ( 5 min )
    Mentions United: Peertube Provider
    I don't often work with videos, especially not on social media. But every now and then I record one with my smartphone, for example at a concert or a soccer match, and want to blog about the event later. I then embed the MP4 files as an asset in the corresponding Markdown. Over the years, a few MB have accumulated and at some point I had to think about where to put them in order to keep the size of the blog under 1GB. Outsourcing to YouTube? I can, but that would be the wrong direction for me. Something on Fediverse or the social web? Of course ... Peertube! On the German instance clip.place operated by adminForge, a channel for the videos was quickly created and uploaded. Basically I only had to change the URL's in the video and iframe tags to the new ones. I don't expect a lot of comment…  ( 5 min )

    Creating an MCP Server Using Go
    In November 2024, Anthropic published a blog post announcing what may be its most significant contribution to the AI ecosystem so far: the Model Context Protocol. According to the official definition on the website: MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP as a USB-C port for AI applications. Just as USB-C offers a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools. Quickly, other players began announcing support for this new protocol: To keep this post concise, I won’t discuss the architecture defined by MCP in detail, but I’ll leave some links at the end for those who want to dive deeper.

    What I Learned Hosting WordPress on an NGINX VPS (and Optimizing It for SEO)
    A few months ago, I started building my online gaming Blog and E-commerce site for the Roblox gaming community. But instead of going the easy route with shared hosting or a managed WordPress provider, I wanted full control. So I spun up a bare Ubuntu VPS, installed NGINX, and started learning everything the hard (but rewarding) way. Why WordPress on a VPS? No bloat: I wanted a clean, fast stack — no unnecessary plugins or GUIs. More control: From PHP version to rewrite rules, I wanted to tweak everything myself. Cheaper in the long run: VPS plans are affordable and scale well. Stack Setup (The Barebones Way) I’m running: Ubuntu 22.04 NGINX PHP 8.2 MySQL Let’s Encrypt SSL WordPress (manual install via wget) No cPanel, no one-click install — just terminal commands, logs, and Google when thin…  ( 4 min )

    Killing Bots at the Gate: Detecting Malicious Crawlers with Nginx
    Bots are a fact of life on the internet. Some are helpful—like search engine crawlers. Others scrape your data, spam your forms, or brute-force your login pages. If you’re self-hosting with Nginx, you don’t need a pricey SaaS WAF to stop them. Here's how to detect and destroy malicious bots using good ol’ Nginx, a few scripts, and some zip-bomb flavor. Nginx logs tell the full story. Make sure you're capturing User-Agent, IP, and paths. log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent"'; access_log /var/log/nginx/access.log main; Now dig through logs for patterns: # Top IPs by request volume awk '{print $1}' /var/log/nginx/access.log | sort | uniq -c | sort -nr…  ( 5 min )
    I’m testing Google Ads before building my SaaS — here’s why (and how)
    Most indie hackers make this mistake: They build a product — then try to find customers. I’m trying the opposite. I launched a landing page first, and immediately started testing demand with paid ads — even before writing a single line of code. Building a product takes time. And if nobody wants it... all that effort is wasted. Instead of waiting until launch, I want answers early: Are people searching for this kind of product? Will they click? Will they leave a lead? How much will it cost me to get one? What I did: Built a simple landing page on Framer in one day Set up a €20 test budget on Google Ads Created a form to collect early leads Tracked everything manually — no complex funnel yet I made a mistake 😅 600 useless clicks later, I paused the campaign. Second try: ✅ High-intent keywords Simple ad copy No display, no video, no smart automation The result? Lower traffic — but real, relevant visitors. And a few leads. Even with €10–20, I got signal: People are searching for this I’m getting a few signups And I can start estimating my customer acquisition cost This will help me decide: Is this idea worth building? What pricing makes sense? What channels work best? Next steps (Hint: talk to them — don’t ghost them.)

    Untangling the AWS VPC Maze: Your 10-Step Network Troubleshooting Guide
    You've launched your EC2 instance. The security group looks perfect. The application should be running. You try to hit the public IP address in your browser, or maybe SSH in... and crickets. Nothing. That familiar sinking feeling hits: "Why can't I connect?" If you've worked with AWS, you've likely been there. Network connectivity issues in Amazon Virtual Private Cloud (VPC) are common, often frustrating, but almost always solvable with a systematic approach. (Intro/Hook: Relatable problem, setting the stage) In the cloud, networking isn't just plumbing; it's the central nervous system of your applications. Your VPC configuration dictates how your resources communicate with each other, with other AWS services, and with the wider internet. A misconfigured route table, a forgotten security g…  ( 10 min )

    Understanding onMouseEnter, onMouseOver, and onMouseMove in React
    Recently, I was building an animated tabs component for my website, something similar to the animated tab switcher found on Vercel’s dashboard (below) I was using Framer Motion’s layout animations to animate a background highlight that follows the active tab. Each tab was a div, and I added onMouseEnter and onMouseLeave event listeners to track which tab was currently highlighted. Simple enough, right? It worked... until I started moving my mouse quickly between the tabs. Sometimes, especially when I moved the mouse at a high speed, none of the tabs appeared to be hovered. The highlight vanished. It was as if my mouse had exited all the elements, even though it was clearly moving over them. That behavior didn’t make sense. So I dug in. And that’s when I stumbled upon the differences betwe…  ( 4 min )
    Cool python syntax techniques
    Did you ever do something that your friends saw and said "Wow, how did you know that?" String formatting and interpolation ✔️ Inline conditionals ✔️ List comprehensions ✔️ Lambda functions ✔️ Type hinting ✔️ ⛓️ String formatting and interpolation The first way that people often learn to join values and strings is the concatenating method: words = "5" concat_str = "This string has " + words + " words" However, this method is not very readable and doesn't work on many languages. Interpolated strings are a way of combinating variables and fixed strings in a more visual way, which can help code insight and debugging.

    1007. Minimum Domino Rotations For Equal Row
    1007. Minimum Domino Rotations For Equal Row Difficulty: Medium Topics: Array, Greedy In a row of dominoes, tops[i] and bottoms[i] represent the top and bottom halves of the ith domino. (A domino is a tile with two numbers from 1 to 6 - one on each half of the tile.) We may rotate the ith domino, so that tops[i] and bottoms[i] swap values. Return the minimum number of rotations so that all the values in tops are the same, or all the values in bottoms are the same. If it cannot be done, return -1. Example 1: Input: tops = [2,1,2,4,2,2], bottoms = [5,2,6,2,3,2] Output: 2 Explanation: The first figure represents the dominoes as given by tops and bottoms: before we do any rotations.

    Test Independence Done Right: How to write truly isolated tests!
    Overview One of the MOST important rules in automation is having independent tests. This means tests should not rely on each other and you should be able to run any test from any suite at any time. In this blog post, I am sharing some proven practices I've picked up over a decade in test automation. Cypress is used for the demos, but the concepts apply to any test automation stack. Special thanks to @Sebastian Clavijo Suero for his great feedback and suggestions! ⚠️ Disclaimer: The techniques and practices shared in this article are based on real-world experience across multiple projects and teams. While they’ve worked well for me and many others, they’re not the only way to approach test isolation, and I’m not claiming these are the best approaches.

    Generative AI requires Skills and Hard Work
    Usually, I'm a nice guy. I roll with the punches, if I can. But, I am so sick of people's attitude toward generative AI. I'm talking about using generative AI for game development -- especially for artwork. It seems that there is a misconception that using AI means that you aren't doing any work and/or your art skills are weak. Frankly, that's bullshit! There are four types of assets that I use in my game: Purchased Assets. I have hundreds of purchased assets -- especially from Itch.io. I'm a bit of a hoarder. Some I buy because I want to use them in a game. Some I buy because they make me smile. Some I purchase because I want to learn from the artist -- I like their style and may want to mimic certain elements of it. (I've never used another artist's work to train an AI!) Howev…  ( 6 min )

However, it's easy to miss critical concepts if you don't spend enough time learning how to do it right. Hugo is a framework, so it has its specificity.

    Stop Using AWS.
    How many times have you seen someone build an MVP with all the cloud bells and whistles, only to watch it go nowhere? The product had Lambda functions. It had API Gateway. It had Cognito.

The truth is simple: you don't need AWS to build something users love. There is a common trap that builders fall into. You read a few blog posts or see a diagram on Twitter and suddenly you think your tiny project needs the same architecture as Netflix. You don’t.

    C# vs Angular: Universal Principles of Dependency Injection
    Introduction Dependency Injection (DI) is a concept so deeply ingrained in everyday programming practices that ignoring it could almost be considered a cardinal sin, on par with neglecting version control. But why has DI become so crucial? DI is one of the key principles enabling the creation of flexible and maintainable applications. The philosophy behind it revolves around freeing code from unnecessary details that tightly couple logical components. Components no longer depend on specific implementations of other parts of the system—they simply declare their needs, and DI provides the required dependencies. The goal here is not just to master a trendy technology but to explore a universal architectural tool whose concepts transcend different ecosystems. Studying DI across multiple lang…  ( 10 min )

    DuckDB: When You Don’t Need Spark (But Still Need SQL)
    The Problem Too often, data engineering tasks that should be simple end up requiring heavyweight tools. Something breaks, or I need to explore a new dataset, and suddenly I’m firing up Spark or connecting to a cloud warehouse - even though the data easily fits on my laptop. That adds extra steps, slows things down, and costs more than it should. I wanted something simpler for local analytics that could still handle serious queries. DuckDB is an open-source, in-process SQL OLAP database designed for analytics. It runs embedded inside applications, similar to SQLite, but optimized for analytical queries like joins, aggregations, and large scans. In short, it goes fast without adding the complexity of distributed systems. Columnar Storage: Vectorized Execution: These two design choices allo…  ( 4 min )

    Docker Bind Mounts: Supercharging Your Development Workflow
    When building containerized applications with Docker, one common frustration developers face is the lack of live updates when editing code. For example, you tweak server.js or a front-end file, but the changes don’t reflect in the running app. Why? Because Docker copies your project files into the container when you build the image. Once the container starts, it runs on that static snapshot—isolated from your host file system. Restarting the container every time you make a change? That’s inefficient. Enter: Bind Mounts. Bind mounts allow you to map a file or directory on your host machine to a path inside your running container. This means: Your container reads real-time code from your host. You can make live changes on your local system, and see them reflected instantly inside your contai…  ( 5 min )

    Simplifying Dictionary Operations with defaultdict in Python
    In Python, working with dictionaries often involves checking whether a key exists before performing operations. This can add unnecessary lines of code and reduce readability. The defaultdict from Python's collections module simplifies this process elegantly. defaultdict? A defaultdict automatically initializes keys with a default value if they don't exist. This means you can start using the dictionary right away without having to check for the existence of keys manually. defaultdict from collections import defaultdict alphabet_count = defaultdict(int) s = "A quick brown fox jumps over a lazy dog while buzzing zebras and vexed wizards quietly fix jammed locks beside echoing drums." for char in s.lower(): if char.isalpha(): alphabet_count[char] += 1 for letter in 'abcde…  ( 5 min )

    Simple Browser Tracking
    ⚠️ Only the technical part is explained. If you care about legality, you're on your own. At the time of writing, this method works in Firefox and Chrome. Tracking users is a touchy topic.

    #5 DP: Adapter
    O que é? O Adapter é um padrão de projeto estrutural que tem como objetivo "traduzir" ou adaptar o funcionamento de um código X para que seja compatível com o código Y. Imagine que você tem várias classes de pagamento que implementam uma interface comum chamada Pagamento — por exemplo: Pix, Ted e Boleto. Agora, sua equipe precisa integrar uma nova forma de pagamento, como PayPal, desenvolvida por outra squad ou vinda de uma biblioteca de terceiros. Essa classe PayPal não implementa a interface Pagamento, e isso quebraria o padrão da sua aplicação. Para resolver esse problema sem modificar a biblioteca externa (o que muitas vezes nem é possível), usamos o padrão Adapter, que atua como um "tradutor" entre as interfaces. Ele faz com que a classe PayPal seja compatível com a interface Pagame…  ( 3 min )

    Mastering CRON Expressions - A Developer's Quick Guide
    CRON expressions are powerful tools for scheduling tasks — from backups to emails — across servers, cloud platforms, and CI/CD pipelines. While they may look cryptic at first, once you decode the pattern, you unlock a whole new level of automation. A CRON expression is a string with 5 space-separated fields (sometimes 6 or 7 depending on the system) that define a recurring schedule. ┌──────── minute (0 - 59) │ ┌────── hour (0 - 23) │ │ ┌──── day of month (1 - 31) │ │ │ ┌── month (1 - 12 or JAN-DEC) │ │ │ │ ┌─ day of week (0 - 6 or SUN-SAT) │ │ │ │ │ * * * * * Expression Meaning 0 0 * * * Every day at midnight */5 * * * * Every 5 minutes 0 9 * * 1-5 9 AM on weekdays 30 14 1 * * 2:30 PM on the 1st of each month @daily Shortcut for 0 0 * * * Symbol Meaning * Every value , List (e.g., MON,WED,FRI) - Range (e.g., 1-5) / Step (e.g., */10 → every 10 units) String Equivalent CRON Description @reboot — Run at system startup @yearly 0 0 1 1 * Once a year @monthly 0 0 1 * * Once a month @weekly 0 0 * * 0 Every Sunday @daily 0 0 * * * Every day at midnight @hourly 0 * * * * Every hour Always test your expressions using tools like crontab.guru or Cronhub. This format changes based on the system. For example, the Quartz CRON scheduler has a slightly different format to support extra capabilities, such as seconds and nth recursive patterns, like the 3rd Friday of the month.

    🔗 Understanding the TCP 3-Way Handshake: The TCP 3-Way Handshake is a fundamental process that establishes a reliable connection between two devices over a TCP/IP network. It involves three steps: SYN (Synchronize), SYN-ACK (Synchronize-Acknowledge), and ACK (Acknowledge). During the handshake, the client and server exchange initial sequence numbers and confirm the connection establishment. TCP (Transmission Control Protocol) is a foundational internet protocol designed to: reliably (no lost or duplicated packets) ✅ Ensure in-order delivery (packets arrive in the order they were sent) ✅ Provide error-checking (detect and fix corrupted data) Unlike UDP (which just throws data out, hoping it arrives), TCP carefully sets up, manages, and closes connections.

A color-shifting hover card is a type of hover effect that changes the background color of a card or element when the user hovers over it. It is a fun and interactive way to add some visual interest to your website or app. The effect is achieved by using CSS gradients and JavaScript to update the card's background color based on the user's cursor position. You can obviously use solid colors instead of gradients, but gradients are more versatile and can be used for more complex effects…  ( 3 min )
    HTML Basics: Learn HTML for Beginners Step by Step

    Smart Textiles 2.0: How the Square Rug Became a Tech Device
    We’re used to seeing technology upgrade our phones, cars, and even refrigerators—but what about rugs? Surprisingly, the square rug is getting a smart upgrade, and it might be one of the most interesting entries into the world of smart textiles and IoT.

    💰 Cost Optimization with AWS Compute Optimizer:
    💰 Cost Optimization with AWS Compute Optimizer. “You can’t optimize what you don’t measure.” — This quote holds especially true in the cloud. In this blog, I’ll walk you through what Compute Optimizer is, how it works, and how I used it in a real-world project to save money without compromising performance. 🔍 What is AWS Compute Optimizer? EC2 instances ⚙️ How Compute Optimizer Works Go to the AWS Console. 🧪 Real-World Use Case: Cost Cutting with EC2 We had 6 EC2 instances of type t3.large in a production environment. These handled various microservices with relatively low average usage but had burst workloads occasionally. Compute Optimizer Analysis: CPU utilization: <10% average Switch to t3.medium We used this migration strategy: Create AMI backups No increase in latency 🛑 Things to Keep in Mind Is this instance intentionally over-provisioned? (e.g., for redundancy or DR) 📦 What About EBS and Lambda? We had a general-purpose gp2 volume attached to our dev environment with almost no IO requirements. Compute Optimizer suggested sc1 (cold HDD), and we tested it for archive-type workloads. ✅ Result: No functional issues, 60% storage cost saved. Lambda In a different project, our Lambda functions had 1024MB memory allocated by default. Compute Optimizer showed average usage around 200MB. We lowered to 512MB, which also reduced the timeout rate and improved cold-start behavior. 📊 How to Track the Savings Use AWS Cost Explorer to monitor actual savings AWS Trusted Advisor → checks for idle load balancers, unused IPs, etc. 🔚 Final Thoughts 🎯 It's free, data-backed, and supports multiple AWS services. In my experience, implementing even 10–15% of the recommendations led to significant savings — without a single service interruption.  ( 5 min )

    Lessons from Building a One-Man Startup: The Evolution of Octal Stream
    Over the course of several years, I embarked on an ambitious solo journey to create a digital education business. What began as a simple idea evolved through multiple iterations—each one teaching me something about technology, process, and the nature of entrepreneurship itself. This is the story of that journey—from Katacoding to Sigmacasts to Octal Stream—and the insights I gained along the way. The concept began with Katacoding, a platform offering live, one-on-one online coding lessons via video calls. While the model had promise, it lacked scalability. That realization led to Sigmacasts, a curated series of educational videos on math and computer science. The production process taught me how to craft educational narratives and use video to communicate abstract ideas. Eventually, these …  ( 5 min )

    AI vs. Human Language: Why AI Will Never Fully Capture Human Communication?
    Artificial Intelligence (AI) has made incredible strides in understanding and generating human language. From chatbots to virtual assistants, AI-powered tools can mimic human conversation, provide customer support, and even write articles. However, despite these advancements, AI will never fully capture human communication. Why? Because human language is deeply rooted in emotions, cultural contexts, creativity, and nuances that AI struggles to grasp. This Blog explores the key differences between AI-generated language and human communication, highlighting why AI will always fall short of replicating human interaction entirely. The Complexity of Human Language Understand sarcasm and irony. AI Lacks Emotional Intelligence: AI vs. Human Emotions Empathy in conversations. Creativity and Storytelling: A Human-Only Domain AI cannot create original ideas. The Power of Personal Experiences Human Storytelling vs. AI The Role of Cultural and Social Influences Keep up with new trends in language. The Importance of Human Connection AI vs. Human Communication Body language and facial expressions. Unintended discrimination in responses. Lack of inclusivity in AI-generated content. Conclusion: AI has revolutionized language processing, but it cannot replace human communication. Our ability to connect emotionally, create original stories, and adapt language based on context makes human interaction irreplaceable. While AI can enhance communication, it will always need human guidance to ensure meaningful, ethical, and culturally aware interactions.  ( 4 min )

    Apple vs Epic Games: Fight for developers freedom
    How it all starts. Back in August 2020, Epic Games added its own way to pay inside Fortnite, skipping Apple’s built-in payment system. This broke Apple’s App Store rules, so Apple removed Fortnite from the store. In response, Epic sued Apple, saying the company had too much monopoly and was stopping fair competition. The courtroom drama went over several years: September 2021: A judge ruled that Apple was mostly right, but one of its rules—stopping developers from telling users about other payment options—was unfair under California law. Apple had to let developers share links to other ways to pay. April 2025: The court said Apple broke that rule again. Even after the 2021 order, Apple still charged a 27% fee on outside payments and made it hard for developers to show other payment opt…  ( 4 min )

    Inside the Minds of AI Agents: How Their Evolving Behavior Reshapes Business Risk
    In today’s fast-moving digital landscape, Artificial Intelligence (AI) agents are no longer just tools—they’re decision-makers, collaborators, and even strategists. But as these systems grow more autonomous and complex, a pressing question arises: Do we truly understand how AI thinks, learns, and evolves? The evolving behavior of AI agents isn’t just a technical curiosity—it’s a critical business risk that leaders must monitor closely. In this article, we’ll dive deep into the inner workings of AI agents, explore how their behavior can shift over time, and what that means for businesses across industries. What Are AI Agents, Really? Unlike traditional software, AI agents learn and adapt. This ability, while powerful, can lead to unpredictable behaviors, especially as agents interact with new data or collaborate with other agents in a shared system. The Evolution of AI Behavior: A Double-Edged Sword Examples of Evolving AI Behavior: Bias amplification: Over time, AI models may reinforce and amplify hidden biases in training data. Unexpected strategy development: AI agents in competitive environments (e.g., simulations, financial markets) may develop unanticipated strategies that break norms or ethical boundaries. These evolving behaviors can introduce operational, ethical, and reputational risks if not properly understood and controlled. Why Business Leaders Should Care Autonomy Can Create Blind Spots Unpredictability Increases Risk Exposure Regulations Are Coming Strategies to Manage AI Behavioral Risk ✅ AI Explainability ✅ Continuous Monitoring ✅ Ethical AI Governance ✅ Simulation & Testing The Future: Human-AI Collaboration with Guardrails The question is no longer “What can AI do?” but “What is my AI actually doing—and why?” Conclusion 🔍 Stay informed, stay prepared. The more we understand AI behavior, the safer—and smarter—our future becomes.  ( 5 min )

    AWS security tips for large scale java angular application
    When building a large-scale Java and Angular application on AWS, we must consider security at every layer from the underlying AWS infrastructure to the application code. Here are some best practices - 1. Identity and Access Management (IAM) with Least Privilege Best Practice: Adopt a strict least privilege approach with our IAM policies. Assign users, roles, and services only the permissions they require, and enforce role-based access control (RBAC). Examples: Do not use root credentials for everyday tasks. Instead, create IAM roles for our services (e.g., EC2, Lambda) and assign specific policies. Policy Example: json Real-Time Scenario: In a large-scale environment, our Java backend might run on an EC2 fleet or containers in ECS/EKS.

    The difference between `@RestController` and `@Controller`
    The difference between @RestController and @Controller in Spring Framework lies mainly in how they handle HTTP responses. @Controller Used for: Traditional MVC (Model-View-Controller) web applications. Returns: Usually returns a View (like JSP, Thymeleaf, etc.). ResponseBody: If you want to return JSON/XML instead of a view, you must use @ResponseBody on the method. Example: @Controller public class MyController { @GetMapping("/hello") public String hello(Model model) { model.addAttribute("message", "Hello, World!"); return "hello"; // returns a view named "hello" } @GetMapping("/api") @ResponseBody public String api() { return "This is JSON or plain text"; } } @RestController Used for: RESTful web services (APIs). Returns: Automatically returns JSON or XML responses. Behavior: It is a convenience annotation that combines @Controller and @ResponseBody. So every method returns the body directly, not a view. Example: @RestController public class MyRestController { @GetMapping("/hello") public String hello() { return "Hello, REST!"; // returns as JSON or plain text } } Feature @Controller @RestController Returns View? Yes (by default) No JSON/XML by default? No (@ResponseBody needed) Yes Use case Web UI applications REST APIs Combines with @ResponseBody Already includes @ResponseBody  ( 3 min )

    Running llama3 in WSL2 using Docker in your PC 🐧🦙🐋
    In order to run Ollama in your local system, the best way is to use docker in the Windows Subsystem for Linux. This is a tutorial going over what needs to be done. This guide will walk you through setting up Windows Subsystem for Linux (WSL) and Docker inside WSL on a Windows machine. Open PowerShell as Administrator and run: wsl --install This installs Ubuntu as the default distribution. If WSL 2 isn't already enabled, this command handles it too. This will install Ubuntu. Once done, restart your PC to complete the setup. After reboot, WSL will launch and prompt you to create a username and password. If it doesn't launch automatically, run: wsl Or launch Ubuntu from the Start Menu. Inside WSL terminal: sudo apt update && sudo apt upgrade -y Instructions taken from Docker Ubuntu Instal…  ( 4 min )
    12.5 Reflection: parameter names
    Nova funcionalidade: Agora é possível recuperar os nomes dos parâmetros de métodos e construtores usando reflection. Como fazer: Use o método getConstructor(...) para obter o construtor desejado. Em seguida, chame getParameters() para obter um array de Parameter. Use getName() para acessar o nome de cada parâmetro. Importante! Por padrão, os nomes exibidos serão genéricos (arg0, arg1). Para ver os nomes reais, é necessário compilar o código com a flag: -parameters Exemplo com flag: javac -parameters Usuario.java Sem essa flag: Antes do Java 8: Dependia de bibliotecas externas, como o Paranamer: Paranamer paranamer = new CachingParanamer(); String[] parameterNames = paranamer.lookupParameterNames(constructor); Vantagens da nova abordagem: Evita dependências externas. Facilita o uso de reflection de forma mais limpa e segura. 🛠️ Como compilar com a flag -parameters: javac -parameters Usuario.java ReflectionTeste.java E depois execute: java ReflectionTeste 🧾 Saída esperada (com -parameters): true: nome true: pontos 🔁 Saída sem a flag -parameters: false: arg0 false: arg1 💡 Importante: Para que os nomes reais dos parâmetros apareçam (nome, pontos), compile com a flag -parameters.

    How to Manage Authentication in a GraphQL API in 2025?
    In the rapidly evolving landscape of web development, managing authentication in a GraphQL API is crucial for securing data and ensuring a seamless user experience. With the growth of microservices and serverless architectures, it's more important than ever to implement robust authentication mechanisms. Here’s a comprehensive guide on managing authentication in a GraphQL API in 2025. GraphQL, a query language for APIs, allows clients to request only the data they need. This flexibility makes it popular in modern web applications. However, it also introduces unique challenges in securing endpoints and managing user access.

    This Week in Cloud: Unexpected AWS Tour
    Not every week is about shipping cool projects, sometimes it’s just about testing. I spent the week running through various LocalStack Pro sample apps to make sure everything worked as expected. What I didn’t expect was to get hands-on with a whole bunch of AWS services I’ve barely touched before (and a few I had honestly never even heard of). SageMaker → Machine learning workflows RDS → Managed relational databases Neptune → Graph databases Step Functions → Orchestration workflows Glue → Data catalog and ETL MQ → Managed message brokers Route 53 → DNS and traffic routing ...plus the usual mix of storage, compute, and API Gateway goodness. What stood out this week was how much you can learn just by doing. I didn’t plan to dive into graph databases or message brokers, but while debugging and tinkering, I picked up quite a bit. Having everything local with LocalStack definitely made that exploration easier and less intimidating. First things first: I need to finish my Meme App (priorities are priorities). Once that’s wrapped, I’d like to turn some of this accidental learning into small demos and share tips on how to explore unfamiliar AWS services without the usual stress. If you’ve ever gone down the AWS rabbit hole and come out the other side with new scars and skills, I’d love to hear your story too. Just hit me up on Twitter or LinkedIn.

    React - Simple Component with Pagination
    A code snippet for a React component with a simple pagination. When user clicks prev/next button, update query string (page, pageSize) via navigate() - this URL update does not reload the page. At first load and when useEffect([location.search]) sees location.search (query string) changed, populateMyList() runs. When populateMyList() fetches data, setMyList() and setLoading() are called. Those setState calls trigger a render to reflect the new data. import React, { useState, useEffect } from 'react'; import { useLocation, useNavigate } from 'react-router-dom'; export function MyList() { //this stores and tracks our data const [myList, setMyList] = useState({ totalCount: 0, data: [] }); const [loading, setLoading] = useState(true); //we need this to get and manip…  ( 3 min )

    How MCP Leverages OAuth 2.1 and RFC 9728 for Authorization
    Authorization isn’t just a checkbox in agentic systems. It’s a make-or-break layer for security, scalability, and trust. Without a clear way to authenticate dynamically, AI agents either hit brittle, hardcoded APIs or introduce serious security gaps. That’s why authorization has been one of the biggest missing pieces in the Model Context Protocol (MCP). When MCP was first introduced, it focused on helping AI agents interact with APIs. But it left out that one critical capability: authorization. For the past six months, the MCP team has been working to change that, building a secure, dynamic authorization layer that can keep up with the unpredictable nature of agentic systems. The new MCP authorization model is based on OAuth 2.1, as expected. But it also adds an important enhancement: supp…  ( 6 min )
    Maybe Your Business Doesn't Need an App.
    Maybe Your Business Doesn't Need an App. Often, when I'm on discovery calls with potential clients, a common question arises: "Do you think building an app for my business is a good idea?" My response can sometimes be neutral—or even disappointing—but there's an essential reason for that honesty. Statistically speaking, about 90% of SaaS (Software as a Service) startups fail. This fact isn't meant to discourage entrepreneurs but to inject a necessary dose of realism. As a software developer, I notice that of all the apps installed on my phone or computer, roughly 90% rarely get opened after the initial installation. Sure, some might be used weekly, like social media apps or games, but only a few become daily essentials. Think about your usage: development tools (Xcode, VS Code), browsers (…  ( 5 min )

    Real-World Blue-Green Deployment: 10 Lessons I Wish I Knew Earlier
    I started experimenting with blue-green deployment months ago—published a couple of slide decks (one, two), read the docs, thought I had it mostly figured out. Spoiler: I didn’t. Now, after rolling it out in real-world systems (and dealing with the chaos that followed), here are the 10 most valuable lessons I’ve learned—what worked, what broke, and how we made it through. Even with Terraform and Ansible, subtle differences sneak in—especially after a few hotfixes. We had OpenSSL versions drift apart, and legacy clients couldn’t connect after a switch. Version control your infra and regularly diff live configs. Schema changes are where blue-green deployments get risky fast. One rollout crashed due to a new JSONB column in green that blue’s ORM couldn’t handle. Solution? Versioned migrations…  ( 4 min )

    Warren Buffett to step down as Berkshire Hathaway CEO by year's end
    Warren Buffett, the CEO of publicly traded investment company Berkshire Hathaway, announced at the company's annual shareholder meeting that he will step down by the end of 2025, and his chosen successor will take over as CEO, pending approval from Berkshire's board of directors. According to CNBC, Buffett reiterated that Greg Abel, the company's vice chairman of non-insurance operations, who was previously named by Buffett as his successor, will take over. The Berkshire founder announced: "The time has arrived when Greg should become the Chief executive officer of the company at year-end, and I want to spring that on the directors effectively and give that as my recommendation." Buffett added that he would stay at the company in an advisory role "but the final word would be what Greg deci…
    Bitcoin miners should pay costs in depreciating currency — Ledn exec
    Bitcoin (BTC) mining firms should hold their mined Bitcoin and use it as collateral for fiat-denominated loans to pay operating expenses instead of selling BTC and losing the upside of an asset that miners expect to surge in price, according to John Glover, chief investment officer at Bitcoin lending firm Ledn. In an interview with Cointelegraph, Glover said that holding onto the BTC carries several benefits including, price appreciation, tax deferment, and the potential to make extra revenue by lending out BTC held in corporate treasuries. The executive added: "If you are mining, you are generating all this Bitcoin. You understand the thesis behind Bitcoin and why it is likely going to continue to appreciate in the future. You do not want to sell any of your Bitcoin." This debt-based appr…
    Ethereum nears key Bitcoin price level that last time sparked 450% gains
    Ethereum’s Ether (ETH) token is approaching a critical price zone against Bitcoin (BTC), which historically marked the beginning of a massive rebound. ETH price fractal from 2019 hints at bottom The ETH/BTC pair, currently trading near 0.019 BTC, is edging closer to 0.016 BTC — the exact level it reached in September 2019 before rallying nearly 450% over the following year. ETH/BTC weekly performance chart. Source: TradingView The current ETH/BTC setup resembles 2019, with both periods marked by oversold relative strength index (RSI), long stretches below key moving averages, and multiyear declines. In 2019, ETH/BTC fell over 90% in the prior two years, driven by the ICO collapse. As of 2025, the pair is down over 80% from its 2021 peak, weighed by skepticism over Ethereum’s switch to pr…
    Why tokenized gold beats other paper alternatives — Gold DAO
    Tokenized gold carries several benefits over other forms of paper gold, including gold exchange-traded funds (ETFs), according to Melissa Song and Dustin Becker, representatives of Gold DAO, a decentralized autonomous organization that facilitates investor access to tokenized gold. In an interview with Cointelegraph, the DAO representatives outlined three major benefits unique to tokenized gold, including 1:1 redeemability for a specific quantity of physical, serialized gold, usage as collateral in decentralized finance (DeFi) applications, and transactional efficiency through on-demand liquidity. "When you buy an ETF, you are betting on the gold price going up, but you do not own any specific gold bar," Song told Cointelegraph. The pair added that the price of gold surged in 2025 due to t…
    Bitcoin mining — Institutions boost investments amid favorable US climate
    Opinion by: Fakhul Miah, managing director of GoMining Institutional The Bitcoin (BTC) mining industry has never been more attractive to institutional investors. Fintech giants are investing in Bitcoin mining rather than just accumulating the asset, all thanks to the favorable regulatory environment in the US and the profitability margin of BTC.  Then, numerous companies are diversifying by allocating computing power to AI, further strengthening their economics and, thus, investment attractiveness. For now, it looks like the future of the foundational layer for the Bitcoin network could mark the new gusher age. Is Bitcoin mining profitable? Bitcoin mining is still profitable. CoinShares, a digital asset investment firm, shared that the average cost to mine 1 BTC for US-listed miners reache…
    After Zora airdrop goes awry, what’s next for Web3 creator economy?
    Onchain social network Zora has built a reputation as a popular tool for artists, musicians and other creatives to monetize their content onchain, but the recent launch of its eponymous ZORA token has left many users confused and dissatisfied. The token’s price tanked shortly after launch, with users and observers complaining about everything from poor communication from the team to the token’s distribution and utility models.  This comes amid an overall decline in interest in the onchain creator economy and a changing perspective on whether blockchain tools like non-fungible tokens (NFTs) are still useful for creatives who want to monetize their work on the blockchain. With creators and builders shifting focus and NFTs no longer selling like they used to, does the ZORA token drop symboliz…
    What is a sealed-bid token launch?
    What are the various methods for launching crypto tokens? Launching a new token is a critical step for any blockchain project. Token launches enable projects to offer their native assets to early users, investors or supporters while securing capital or encouraging community growth.  From initial coin offerings (ICOs) to fair launches and airdrops, each approach carries different levels of transparency, accessibility and risk. Since projects differ in their goals and target communities, several token launch models have evolved over time.  Some focus on decentralization and wide community offering, while others aim for optimized fundraising or targeted allocation. Elements such as market swings, bot interference and regulatory pressures influence how…
    Deribit eyes US expansion under crypto-friendly Trump admin: FT
    Deribit, the world’s largest crypto options exchange, is weighing an entry into the US market, encouraged by what it sees as a friendlier regulatory climate under President Donald Trump’s administration, according to a recent Financial Times report. The Dubai-based exchange, which processed $1.3 trillion in notional volume last year, is “actively reassessing potential opportunities” in the United States, CEO Luuk Strijers told the FT. He cited the “recent shift toward a more favorable regulatory stance on crypto in the US” as a key motivator behind the decision. Deribit’s potential plan to expand into the US comes amid reports that Coinbase is in advanced negotiations to acquire the platform. In a March 21 report, Bloomberg said both companies have notified regulators in Dubai, where Derib…
    Over 70 crypto firms join forces to tackle big tech’s AI monopoly
    In a move that hopes to challenge Big Tech’s grip on artificial intelligence, AI agent protocol Thinkagents.ai has launched a new open-source framework for building onchain agents that operate autonomously across decentralized networks. While traditional systems aim to restrict data ownership and platform abilities for their users, Thinkagents.ai is creating an interoperable ecosystem owned and controlled by its users. For Mike Anderson, core contributor at THINK, the Think Agent Standard is the future of AI. Anderson and his team developed the Think Agent Standard to enable millions of autonomous onchain AI agents to transact and communicate. The protocol now has over 70 companies, like Arbitrum and Yuga Labs, on board to help out.  The platform is now live, allowing developers, enterpris…
    Arizona governor vetoes bill to make Bitcoin part of state reserves
    Arizona Governor Katie Hobbs has vetoed a bill that would have allowed the state to hold Bitcoin as part of its official reserves, effectively ending efforts to make Arizona the first US state to adopt such a policy. The Digital Assets Strategic Reserve bill, which would have permitted Arizona to invest seized funds into Bitcoin (BTC) and create a reserve managed by state officials, was formally struck down on Friday, according to an update on the Arizona State Legislature’s website. “Today, I vetoed Senate Bill 1025. The Arizona State Retirement System is one of the strongest in the nation because it makes sound and informed investments,” Hobbs wrote in a statement aimed at Warren Petersen, the President of the Arizona Senate. “Arizonans’ retirement funds are not the place for the state t…
    Vitalik wants to make Ethereum ‘as simple as Bitcoin’ in 5 years
    Ethereum co-founder Vitalik Buterin called for simplifying Ethereum’s base protocol, aiming to make the network more efficient, secure and accessible, drawing inspiration from Bitcoin’s minimalist design. In a blog post titled “Simplifying the L1,” published on May 3, Buterin laid out a vision to restructure Ethereum’s architecture across consensus, execution and shared components. “This post will describe how Ethereum 5 years from now can become close to as simple as Bitcoin,” Buterin wrote, arguing that simplicity is key to Ethereum’s resilience and long-term scalability. While recent upgrades like proof-of-stake (PoS) and Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) integration have made Ethereum more robust, he said that technical complexity has led to bloat…
    Apple softens crypto app rules, 'hugely bullish' for crypto industry
    Crypto app developers are now free to direct users to payments outside of Apple’s ecosystem without restrictions or hefty fees, after a United States district judge ruled that Apple violated an injunction in its antitrust legal battle against Epic Games. “The Court finds Apple in willful violation of this Court’s 2021 Injunction, which was issued to restrain and prohibit Apple’s anticompetitive conduct and anticompetitive pricing. Apple’s continued attempts to interfere with competition will not be tolerated,” US district judge Yvonne Gonzalez Rogers said in an April 30 court filing. Apple must make changes “effective immediately” “Effective immediately, Apple will no longer impede developers’ ability to communicate with users, nor will they levy or impose a new commission on off-app purch…
    Bitcoin bros at 'the club' may stop US gov’t from buying BTC — Arthur Hayes
    BitMEX co-founder Arthur Hayes says the United States is unlikely to add more Bitcoin to its reserves beyond what it has already seized due to the country’s high debt levels and the stereotype behind “Bitcoin bros.” “I’m not really into the whole Strategic Reserve situation,” Hayes said in a May 1 interview. Hayes doubts any government announcing print money plans for Bitcoin  “The United States is a deficit country; the only way they can do a Strategic Reserve is not sell the Bitcoin they took from people, fine, that’s 200,000 Bitcoin,” he said. Arthur Hayes spoke to Kyle Chasse on his crypto interview series. Source: Kyle Chasse However, Hayes said it’s hard to imagine any “properly elected” politician openly announcing that the government plans to print money to buy Bitcoin (BTC). “Espe…

    Cross-Platform Software Development – Part 1: Yes, Bytes Can Be 9 Bits
    When we say cross-platform, we often underestimate just how diverse platforms really are. Did you know the last commercial computer using 9-bit bytes was shut down only 30 years ago? That was the PDP-10—still running when C was dominant, C++ was just emerging (but not yet standardized), Java hadn’t launched (just one year before its release), and Python was still in development (two years before version 1.0). That kind of diversity hasn’t gone away—it’s just shifted. Today: There are 35+ active CPU architecture families: x86/64, Arm, MIPS, RISC-V, Xtensa, TriCore, SPARC, PIC, AVR, and many more Some use unusual instruction widths (e.g., 13-bit for Padauk’s $0.03 MCU) Not all CPUs support floating-point—or even 8-bit operations And beyond the hardware: 15+ actively used IDEs 10+ build…  ( 5 min )

    My top 5 VScode extensions
    Hi there, I wanted to make this post to recommend some tools that helped me personally as a React Developer over the past 3 years. LinkedIn This article will only cover VS code extensions that helped me during development. Some of these tools were introduced to me by a friend of mine. You can search for them in the VS extension marketplace 👍 It integrates Draw.io into your VScode. Making creating diagrams a lot easier. This tool is useful for creating a mockup design for the frontend of the web application. This is probably one of my favorite Git VScode extensions. A really great tool for visualizing your Git repository commits. I use it to track the commits I made. If you are working with another developer, you can see the commits made by each other in different color trees. This is a tool that has helped me categorise my projects. I have made a lot of projects and they tend to be scattered. This tool helped me organise them into blocks. Clicking on them takes me to the project workspace immediately. One of my favorite tools in my VScode workspace. This extension allows you to store you previous terminal session. You can create a configuration, these configuration can store a set of terminal commands. This is great for variety of functions, like Dockerization, Database migration, and API testings. This is probably my favorite tool out of all the extensions. It prevents the need to add a console.log in my JS files. I can see the output clearly in the console. It boosts my productivity a lot , and I recommend it the most. I hope this article helped with your workspace productivity. Happy coding ! 😄  ( 3 min )

    [Parte 3] Enviando dados entre aplicações com Module
    Na parte 1 desta série, vimos como o Module Federation permite compartilhar componentes entre diferentes aplicações sem precisar instalar pacotes ou duplicar código. Agora, vamos dar um passo além: como enviar dados de uma aplicação para outra. Imagine que você tem dois apps: 🔵 MF Consumer  — quem consome um componente remoto 🟢 MF Provider  — quem disponibiliza esse componente conforme a imagem abaixo: Vamos supor que o MF Provider tenha um componente chamado App que precisa exibir os dados de um usuário ( nome e email ). Esses dados vêm diretamente do MF Consumer. No MF Consumer, tem o seguinte: MF Consumer Aqui, criei um objeto user e passei como props para o componente Provider , que está vindo do MF Provider. No lado do MF Provider , defini o tipo das props ( ProviderProps ) e usei os dados recebidos normalmente, como faríamos em qualquer componente React, como segue: MF Provider Não é magia. É só React com Module Federation! Ao consumir um componente remoto, você ainda pode passar props normalmente, como se ele fosse local. Isso funciona porque, por baixo dos panos, o Webpack cuida de toda a importação remota — mas o React continua funcionando do jeito que a gente conhece. Com isso, conseguimos: Importar um componente remoto com Module Federation Passar dados para esse componente via props Exibir esses dados no MF Provider como se tudo estivesse rodando no mesmo app Acompanhe AQUI como ficou o resultado final. No próximo artigo, vou mostrar como esse padrão pode ser estendido para eventos e callbacks entre MF Consumer e MF Provider (ex: o usuário clica em algo no Provider e o Consumer reage). 💬 Curtiu?

    Containerized Symfony & Vue.js environment with DDEV
    For the past year or so, DDEV has been my go-to tool for setting up a development environment.

    No meu artigo anterior, mostrei como montei um projeto com Micro Frontends usando Rsbuild, Module Federation, pnpm e Lerna , tudo rodando num monorepo. Agora, quero dar um passo além e explicar o “porquê” dessa escolha. É uma forma de compartilhar código entre diferentes aplicações em tempo de execução. Funciona como se um app pudesse importar um componente diretamente do outro — sem instalar, copiar ou duplicar código. Exemplo real no meu repositório: 📦 mf_provider(chamo de componente filho): expõe um componente Button 📦 mf_consumer_(_chamo de componente pai): consome esse mesmo Header, remotamente, sem precisar tê-lo no código local ✅ Evita reescrever os mesmos componentes em diferentes apps (pelo menos tenta) ✅ Permite deploys independentes (independência de times) ✅ Melhora a escalabilidade de grandes projetos ✅ Facilita refatorações e testes A/B isolados ✅ Acelera o desenvolvimento com reuso real de UI e lógica “Você não precisa de Micro Frontends… até precisar.” Nem todo projeto precisa disso. 🔸 Se o projeto é pequeno e centralizado, pode ser complexidade desnecessária 🔸 Se as equipes compartilham tudo e fazem deploy juntos, MF talvez seja overkill 🔸 Se o bundle não é um problema, pode usar libs compartilhadas internas 🚀 Quer ver isso funcionando de verdade?

    Refactor-First, Feature-Last: Conversing with Code
    Two months into my no-code-writing development experiment, I've started to reflect on what I've gained and lost in the process. There are clear wins: faster prototyping, more exploratory design conversations before touching code, and almost no actual coding (which is a huge relief, I'm more of an organize-ideas person, not a coder). I followed the tools' lead intentionally, curious to see what they had to offer. But in doing so, I slipped back into early-career patterns, prioritizing feature work and not handling code smells up front. I lost my Monday-ness. I'm a code whisperer. A wild west code wrangler.

    Micro Frontends + Rsbuild + Module Federation em um Monorepo? Temos!
    💡 Quer estudar, prototipar ou estruturar um projeto com MF (Microfrontend) de forma modular e performática? Nos últimos dias, mergulhei em um experimento que pode facilitar (e muito!) a vida de quem trabalha com micro frontends no dia a dia. 🎯 Criei um repositório open source usando: Rsbuild (alternativa moderna e rápida ao Webpack) Module Federation para isolar e compartilhar componentes entre apps pnpm + Lerna pra orquestrar tudo de forma leve e organizada 📂 Estrutura simples, mas poderosa: apps/mf_provider: expõe componentes apps/mf_consumer: consome via Module Federation Tudo rodando em paralelo com pnpm dev 🔗 Confere lá e, se curtir, arrocha um like ou manda feedback! Repositório no Github O pnpm tem um recurso bem legal chamado Catalogs. Ele serve para definir versões de dependências como constantes, que podem ser reutilizadas nos módulos internos dentro do package.json de cada projeto.

    What Happens When AI Becomes the Client?
    Most APIs were built for humans. We wrote docs assuming someone would read them. We wrapped our endpoints in auth flows and user interfaces. We expected a person, or maybe a service, on the other side. But that’s already changing. AI models are now consuming APIs directly. Not as passive data readers, but as active participants. They parse user intent, synthesize context, and trigger backend actions. They're not just clients. They're intermediaries. And that changes everything. When models call APIs, natural language stops being enough. We like to imagine that models “understand” prompts, but in practice, they just compute probabilities over sequences of text. They don’t grasp nuance the way humans do. A tiny shift in phrasing can derail the whole interaction. That makes coordination betwe…  ( 4 min )
    Leaders Are Overlooking This Crucial Factor in AI Readiness

HydratedDocument • Wraps your base type T with Mongoose’s document helpers. • Use it for any function that deals with real, database-backed For example, in a repository interface you might write: export interface IUserRepository { findOneByEmail(email: string): Promise; findById(id: Types.ObjectId): Promise; create( createUserDto: Pick, ): Promise; } Here, each method clearly promises a “live” Mongoose document (with built-in methods) while elsewhere you can rely on User for pure data shapes—keeping your boundaries and types crystal clear.

    Predicting Crop Yield using Machine Learning
    Sure! Here's a DEV.to style blog post for your project Crop Yield Prediction: An ML project to empower smarter agriculture decisions GitHub Repo → Agriculture remains the backbone of the Indian economy, yet farmers still face unpredictable yields due to varying environmental and input conditions. To tackle this issue, I built a machine learning model that predicts crop yield based on historical and input-based features. This project is simple, beginner-friendly, and practical. "How can we accurately predict crop yield based on inputs like rainfall, fertilizer, and pesticide use?" Farmers often rely on experience or guesswork. This model helps bring data-driven decision-making to the field. The dataset includes: Area Production Crop Year Rainfall Fertilizer Pesticide 📌 Categorical features are label-encoded for model compatibility. Python 🐍 Pandas & NumPy Scikit-learn Matplotlib (optional for plots) I trained and evaluated three regression models: Linear Regression Random Forest Regressor Gradient Boosting Regressor ✅ Best performer Evaluation Metrics: R² Score Adjusted R² RMSE Gradient Boosting gave the highest R² score on the test set and was chosen as the final model. The script allows users to input values for the features and get instant yield predictions.

    3.4 Stronger Security Notions (Introduction to Modern Cryptography Jonathan Katz and Yehuda Lindell)
    3.4.1 Security for Multiple Encryptions Simple experiment, obviously that This experiment shows that, ideally, a secure encryption scheme should give an attacker a probability of guessing bit b, tending to 1/2 (or 50%). important: Definition 3.18 says that a private key encryption scheme is secure when used repeatedly if an adversary (e.g. hacker) cannot distinguish the encryption of two different sets of messages. 1.Security with multiple encryptions: The enemy selects two sets of messages (for example, two lists). One of them is encrypted, and the enemy is trying to guess which one it is. If the scheme is secure, his chances of guessing are only slightly better than just flipping a coin (that is, 1/2 + very small value). Comparison with single encryption (Definition 3…  ( 5 min )

    Queues vs Topics
    In the world of software development—especially with distributed systems and microservices—asynchronous messaging has become essential for building scalable and resilient applications. Two of the most common messaging patterns are queues and topics. While they might sound similar, their behavior and use cases are quite different. In this post, I’ll explain what they are, how they differ, and when to use each one. A queue follows a point-to-point communication model: messages are sent by a producer and consumed by only one consumer. Once a message is processed, it is removed from the queue. Key characteristics: Each message is processed by one and only one consumer. Guarantees single delivery of each message. Useful for load balancing between multiple consumers.

    Demystifying Entity Transaction & Flush in Spring Boot: Are You Using It Right?
    When working with Spring Boot and JPA, understanding how transactions and the 𝗳𝗹𝘂𝘀𝗵() operation interact can make or break your application's data consistency and performance. Yet, I often see even experienced developers overlook the nuances! Many believe that committing a transaction is the only way to persist changes to the database. However, the 𝗳𝗹𝘂𝘀𝗵() method forces the persistence context to synchronize with the underlying database immediately-without ending the transaction. This can be a game-changer for scenarios where you need to validate constraints or trigger database actions before the transaction completes. But here’s the catch: improper use of 𝗳𝗹𝘂𝘀𝗵() can lead to unexpected behaviors, performance overhead, or even data inconsistencies if not handled carefully. It's crucial to know when and why to use it, especially in complex microservices or batch processing environments. How do you approach transaction management and flushing in your Spring Boot projects? Have you ever faced a tricky bug or performance issue related to this?

    PostgreSQL vs. Qdrant for Vector Search: 50M Embedding Benchmark
    Vector search is becoming a core workload for AI-driven applications. But do you really need to introduce a new system just to handle it? We ran a performancebenchmark to find out: comparing PostgreSQL (using pgvector + pgvectorscale) with Qdrant on 50 million embeddings. Sub-100ms query latencies 471 queries per second (QPS) on Postgres—11x higher throughput than Qdrant (41 QPS) Head to the full write-up for a deep dive into our vector database comparison. At 99% recall, Postgres delivers sub-100ms query latencies and handles 11x more query throughput than Qdrant (471 QPS vs. Qdrant’s 41 QPS). The results show that thanks to pgvectorscale, Postgres can keep up with specialized vector databases and deliver as good, if not better performance at scale. Learn more about why Postgres wins for AI and vector workloads. How? We built pgvectorscale to push Postgres to its limits for vector workloads—without compromising recall, latency, or cost-efficiency. It turns your favorite relational database into a high-performance vector search engine. ✅ No extra systems. ✅ No new query languages. ✅ Just Postgres. We used RTABench to run a transparent, reproducible evaluation—designed for real-world, high-scale workloads. Curious about the architecture behind it all? 👉 Read our whitepaper on building Timescale for real-time and AI workloads It dives into how we engineered Timescale to handle time-series, vector, and relational data—all in one Postgres-native platform.

    Demystifying HTTP for Web Developers — Part 1
    What is HTTP and How a Request Travels Across the Web HTTP is the foundation of everything we build and interact with on the web — whether it’s a static website, a complex Single Page Application (SPA), a RESTful API, or a modern mobile app. Every user action that triggers data exchange — from submitting a login form to loading an image — ultimately depends on HTTP. Despite this, many developers treat HTTP as a black box: something that “just works” behind the scenes. While abstraction is useful, serious web developers must move beyond it. Understanding how HTTP actually operates — from how requests are structured, to how connections are established, to how responses are transmitted — is essential for building high-quality, secure, and performant applications.

AI dating pictures refer to profile photos that are either: ✅ Generated entirely by AI — using tools like AI portrait generators or avatars based on your real face. ✅** Enhanced or edited by AI** — improving lighting, removing blemishes, sharpening features, or even subtly reshaping facial features. These photos aim to make you look more appealing wit…  ( 4 min )
    Update currency Exchange Rate in Dataverse... simplified! 😊
    When I started working with Dynamics CRM, ages ago, there were 2 topics that were the nightmare of all CRM devs: Multi currency, aka exchange rate management Time-zone management Ages have passed, but those topics keep staying in the top 5 chart of my headaches-giver topics. Just today, scrolling in my LinkedIn wall, I've found an interesting article from Nick Doelman that pointed to another article from 2021 where he solved the long-standing issue of updating exchange rates in the platform in an way that is straightforward elegant deterministic fast to set-up and, above all, free! It's just a matter of leveraging the right tools, that in this case are: https://exchangeratesapi.io/: a website that provides daily updated exchange rates with a compelling licensing model that allows up to 100 api calls per month for free! a simple Power Automate flow.

    I Lost It All - My Tech Story
    Imagine losing everything, like you went back to square one, everything lost and down the drain because of one small, avoidable mistake. Not a catastrophic accident, not a once-in-a-lifetime tragedy, but a series of tiny, seemingly harmless decisions that snowballed into something irreversible. This is my story. I had just graduated from university, full of fire and ambition. My degree wasn’t in tech, but I was drawn to the world of possibilities I saw in it. This was in the early 20-teens, and the buzzword floating everywhere was “Fullstack Developer.” YouTube was overflowing with success stories, “I went from zero to six figures in a year,” “How I became a Fullstack developer without a CS degree.” It was intoxicating. The idea that I could break out of the trenches, skip the struggle, a…  ( 6 min )

    Sustainable Kubernetes workload with Kepler
    I have covered eBPF in my previous article. In this post, I'll be covering Kepler specifically, which part of CNCF ecosystem. Kepler is a monitoring and observability tool designed for Kubernetes clusters that uses eBPF to track the resource usage of containers and nodes. Unlike traditional monitoring solutions, which often rely on metrics collection agents running in user space, Kepler utilizes eBPF to gather resource consumption data directly from the kernel. This results in high precision and low overhead, which is essential for cloud-native environments. Kepler is particularly useful for: Resource Efficiency: Kepler provides detailed resource usage metrics for containers and Kubernetes workloads, allowing users to optimize resource allocation and avoid over-provisioning.

Partially because js can be a pain but mostly because I was a dingus. .json files? You might be laughing a bit here. Of course .json and js goes hand in hand. Since the beginning of time we have used .json files to throw in config, mock data or see how many levels of data-indentation we can reach before we go crazy. Well, what I want to do is have a data.json file where I "mock" all the data I want/need for a page so: In practise this means I can simply import my file, and since I am not crazy and love using TypeScript, I can also type my data: import rawData from "./assets/data.json"; const myData: UserAboutMe = rawData as UserAboutMe; Agai…  ( 4 min )
    Ace Web Academy vs. Self-Taught Web Design: Why Structured Learning Wins Every Time
    If you’ve ever tried learning web design through free tutorials, YouTube videos, or Reddit threads, you know the struggle. You start with enthusiasm, binge a few lessons, and then… confusion. What’s the difference between Flexbox and Grid? Why does your CSS break on mobile? How do you even land a job after this? You’re not alone.

    Bitcoin Price and Nonfarm Payrolls: What Developers Should Monitor in Volatile Macroeconomic Conditions
    Bitcoin (BTC) continues to face downward pressure as investors await the upcoming U.S. Nonfarm Payrolls (NFP) report, scheduled for release on Friday. For developers working in blockchain and fintech infrastructure, this is more than a market headline—it’s a potential stress point for applications reliant on real-time price data, order execution, and network performance. Understanding these macroeconomic triggers is critical for building resilient crypto-native systems. Bitcoin is currently trading near the $59,000–$60,000 support zone after facing rejection from resistance at approximately $63,000 earlier this week. Despite brief recoveries, sentiment remains cautious ahead of economic data releases. Key technical indicators: Short-term trend remains bearish with lower highs forming on th…  ( 4 min )

    Interfaces in java
    🧵 Interfaces in Java, explained like you're 5! 1️⃣ Imagine a Pizza Menu 🍕 You walk into a pizza place and see a menu. The menu promises what pizzas they offer—but doesn’t make them yet. An interface in Java is like that menu: it defines what a class should do, but not how! The menu says: "All pizzas must have cheese 🧀" "All pizzas must be bakeable 🔥" Any chef (class) who follows this menu must fulfill these rules! In Java, we call this "implementing an interface." 3️⃣ Multiple Menus, One Chef! A chef can follow multiple menus (interfaces): Italian food menu 🍝 Fast food menu 🍔 Similarly, a Java class can implement many interfaces at once! (Unlike inheritance, where you only get one parent.) 4️⃣ But… What If the Chef Cheats? 😱 If a chef says, "I’ll follow the pizza menu!" but doesn’t add cheese… BIG PROBLEM! Java won’t allow this—it forces the class to implement every method in the interface, or the code won’t compile! What if some pizzas usually have tomato sauce, but not always? Interfaces can now provide default methods—like a "standard recipe" that chefs can override if they want! java interface Pizza { default void addSauce() { System.out.println("Adding tomato sauce!"); } }  ( 3 min )
    Building Optional from scratch
    From this article 2 Minute Tips: The Dark Secret of Optionals I got to know that the Optionals are nothing but an Enum . I started experimenting: How can we build Optional from scratch You might have heard of Schrödinger’s Cat — the thought experiment where a cat in a box is both alive and dead until you check. That's basically an Optional, right? A value that might exist... or not. So, let's turn this idea into code: enum 📦 { case 😺(Value) case 😵 init(_ from: Value) { self = .😺(from) } } Now we can do: let x: 📦 = .😺(123) let y: 📦 = .😵 But that's not quite as convenient as Swift's native syntax: let x: Int? = 123.

    The Ultimate Guide to Creating a Flawless Mobile App UI/UX Design
    The success of a mobile app heavily depends on its user interface (UI) and user experience (UX). A well-designed app is intuitive, engaging, and keeps users coming back. On the other hand, a poorly designed app frustrates users, leading to uninstalls and negative reviews. With millions of apps competing for attention, a flawless UI/UX design can be the game-changer that sets your app apart. Users appreciate an app that is easy to navigate. A cluttered and confusing interface overwhelms users, leading to higher bounce rates. Simplicity doesn’t mean your app should be bare-bones, but rather that it should be free from unnecessary elements that distract from the core functionality. Minimize distractions by using a clean and structured layout. Every element should have a clear purpose. Ensure …  ( 6 min )

    Why ARP Matters !!!
    We need ARP (Address Resolution Protocol) to enable communication between devices on a local network. Specifically, ARP is used to map an IP address (logical address) to a MAC address (physical address), which is necessary for data transmission at the data link layer. ARP is a Layer 2 protocol used in IPv4 networks to map a known IP address to its corresponding MAC (Media Access Control) address. While IP addresses help devices find each other logically, MAC addresses are what Ethernet networks use to actually deliver packets. ARP acts as the translator between these two. IP works at Layer 3 (Network Layer) but to actually send data over Ethernet (Layer 2), the system needs the MAC address of the destination device. When a device wants to communicate with another device on the same netwo…  ( 5 min )

    Scripting Series – Part 4 of 8
    Welcome to part 4 in the series of shell scripting. Today we will look at a script that goes through an array with complex values. Complex values such as spaces, apostrophes, and quotes. Scripting is the process of writing a set of instructions in a programming or scripting language to automate tasks that would otherwise be done manually. In the context of shell scripting, these instructions are written for the command-line shell, allowing users to perform complex operations - like file management, backups, or software installations - with just a single script execution. It's a powerful tool for saving time and ensuring consistency in system administration and development workflows Create the script in VIM, complex_list.sh Write and save the script in VIM. We can check whether it has been created by doing ls -ltrh. Give the permission so the script can be executed. If we then do a ls –ltrh we can see the script has gained a green colour, meaning that it is now executable. Output after executing the script by using the command ./ Stay tuned, part 5 in the series coming tomorrow!

    🚀 Introducing SaaSLaunchpad: A Next.js Boilerplate Built for Freedom, Not Lock-In
    Excelorithm, we build custom software solutions for startups, SMEs, and enterprise clients alike. And as the technical head here, I’ve seen a recurring pain point — many teams, including our own, spend way too much time setting up the basics of a SaaS product: authentication, subscriptions, dashboards, role management, notifications... Sure, there are tons of SaaS starter kits out there, both free and premium. They promise speed — and often deliver — but usually at a hidden cost: vendor lock-in. Many popular boilerplates rely on proprietary services, paid APIs, or tightly coupled ecosystems.

    Catalysis Node Operators Explained: The Backbone of a Scalable Web3 Ecosystem
    INTRODUCTION: But exactly is the purpose of the Node Operators in the Catalysis Ecosystem? well let's get into that now. They power the services (AVSs) by doing important technical tasks. They also help protect the network by locking up funds (called staking)—this keeps them honest. If they do something wrong, they can lose money so they have a strong reason to act fairly. I'm pretty sure at this point you can fairly understand why they are called the backbone of the network. Basically without them nothing would work. HOW DOES CATALYSIS WORK IN RELATION TO THE NODE OPERATORS? Normally, running these services on many platforms is complicated and expensive. Catalysis simplifies this by giving them one tool (Catalyst-CLI) to manage everything in one place. Think of the (Catalyst-CLI) li…  ( 4 min )

I was exactly at that point, annoyed by constant need to ssh into my server to check one log line. I've wanted to play with Grafana ecosystem for a while, too. So it seemed to be the perfect moment. In this post, I’ll walk you through a simple and minimal setup that streams my Node.js application's logs into the Grafana Cloud dashboard using Grafana Alloy and Loki. This is what my final setup looks like: Now let’s break down h…  ( 5 min )

    838. Push Dominoes
    838. Push Dominoes Difficulty: Medium Topics: Two Pointers, String, Dynamic Programming There are n dominoes in a line, and we place each domino vertically upright. In the beginning, we simultaneously push some of the dominoes either to the left or to the right. After each second, each domino that is falling to the left pushes the adjacent domino on the left. Similarly, the dominoes falling to the right push their adjacent dominoes standing on the right. When a vertical domino has dominoes falling on it from both sides, it stays still due to the balance of the forces. For the purposes of this question, we will consider that a falling domino expends no additional force to a falling or already fallen domino. You are given a string dominoes representing the initial state where: dominoes[i] = …  ( 25 min )

    Spring JPA - @EntityGraph
    By default, Spring Data JPA loads related data lazily, which can cause the N+1 problem — one query for the main data and more for each related item. @EntityGraph annotation fixes this by letting you load related data in a single query, without changing your entity mapping. It’s simple, improves performance, and avoids writing custom JOIN FETCH queries. Let’s say you have a Post entity that references an Author. Entities @Entity public class Post { @Id private Long id; private String title; @ManyToOne(fetch = FetchType.LAZY) private Author author; } @Entity public class Author { @Id private Long id; private String name; } Repository public interface PostRepository extends JpaRepository { // attributePaths specifies related entities to eagerly load @EntityGraph(attributePaths = {"author"}) List findAll(); } Now, if you create a simple controller to return all posts and have SQL logging enabled, you'll see the queries printed in the console. With @EntityGraph, only one query runs to fetch both the post and its author. Without it, multiple queries are executed — one for the posts and one for each author — which is the N+1 problem. ✅ Using @EntityGraph Only one query — fast and efficient. select p.id, p.title, a.id, a.name from post p left join author a on p.author_id = a.id 🚨 Not Using @EntityGraph N+1 queries — slow and wasteful. select * from post; select * from author where id = ?; select * from author where id = ?;  ( 3 min )

    Best Alternative to pprint: Introducing SetPrint for Better Python Data Formatting
    Issues with Existing Formatting Tools When working with data structures like lists or NumPy arrays in Python, the standard print or pprint, or even external tools like rich, often fail to provide a clear view of the entire structure, especially when dealing with multi-dimensional arrays or deeply nested data, making it easy to lose track of which element corresponds to which. Let's consider the following example as an illustration. sample = [ {"user": {"id": 1, "name": "Alice", "scores": [95, 88, 76]}}, {"user": {"id": "002b", "name": "Bob", "scores": [72, 85, 90]}}, {"bug_user": {"id": [3], "name": "Charlie", "scores": [100, [50, 40], 70]}}, ] — The “Pitfalls” of Data Structures Python's lists, dictionaries, and NumPy arrays are fine to work with for simple structures.…  ( 5 min )

    Stars align for Bitcoin rally to $100K, but futures traders exercise caution — Here’s why
    Key takeaways: BTC hit $97,900 due to soaring institutional investor demand, but futures pricing shows traders aren't confident in a sustained rally. Macroeconomic risks and global trade tensions cap bullish sentiment despite $3.6 billion in spot BTC ETF inflows. BTC options lean bullish, suggesting big players expect upside, but their caution keeps leverage use low. Bitcoin (BTC) broke out of a tight trading range between $93,000 and $95,600 on May 1, following six days of limited movement. Despite reaching its highest price in ten weeks at $97,930, sentiment remains neutral according to BTC derivatives indicators. This price action has occurred alongside significant net inflows into US spot exchange-traded Bitcoin funds (ETFs). Some of the disappointment among traders can be attribut…
    Pro-crypto senator pushes back on Trump's memecoin dinner — Report
    Senator Cynthia Lummis and at least one other Republican in Congress are reportedly critical of US President Donald Trump for offering the top holders of his memecoin a dinner and White House tour. According to a May 2 CNBC report, Lummis said the idea that the US president was offering exclusive access to himself and the White House for people willing to pay for it “gives [her] pause.” She wasn’t the only member of the Republican Party to be critical of Trump’s memecoin perks, announced on April 23, roughly three months after the then-president-elect launched the TRUMP token.   “I don’t think it would be appropriate for me to charge people to come into the Capitol and take a tour,” said Republican Senator Lisa Murkowski, according to NBC News. Despite Lummis’ reported “pause” over the p…
    Ethereum’s era of crypto dominance is over — LONGITUDE panel
    Ethereum’s relative dominance among layer-1 (L1) blockchain networks has declined, resulting in an “open race” to become the leading Web3 platform, according to Alex Svanevik, CEO of data service Nansen. “If you’d asked me 3–4 years ago whether Ethereum would dominate crypto, I’d have said yes,” Svanevik said during a panel discussion at the LONGITUDE by Cointelegraph event. “But now, it’s clear that’s not what’s happening.” Ethereum is still the most popular L1 network. According to data from DefiLlama, its roughly $52 billion in total value locked (TVL) represents 51% of cryptocurrency residing on blockchain networks. However, Ethereum’s dominance has diminished sharply since 2021, when the L1 controlled as much as 96% of aggregate TVL, the data shows.  Panelists at the LONGITUDE by Coin…
    Most shops in Cannes to accept crypto by summer this year — Web3 exec
    Merchants in Cannes, France, the site of the international Cannes Film Festival, are set to begin accepting crypto payments by summer this year in an effort to attract clientele with high disposable income by modernizing the city's commercial payment ecosystem. According to Artem Shaginyan, founder and head of strategy of Web3 payment company Lunu Pay, the Cannes municipal government is aiming for a 90% adoption rate among local merchants. The executive also told Cointelegraph: "This is a big signal. When a city like Cannes, known globally for culture and commerce, starts integrating crypto at scale, it shows that Web3 payments aren’t just a niche thing anymore. It’s about proving that crypto can work in everyday settings, not just online or in theory." In February, Cannes Mayor David Lisn…

    Bitcoin data, macroeconomic charts point to new BTC all-time high ‘in 100 days’ — Analysts
    Key Takeaways: Analyst predicts a low VIX ( Bitcoin network economist Timothy Peterson raised Bitcoin’s (BTC) chances of hitting a new high in 100 days, and he maintains an optimistic outlook in 2025.  In an analysis shared on X that ties BTC’s price action to the CBOE Volatility Index (VIX) —an indicator that measures 30-day market volatility expectations — the analyst pointed out that the VIX index has dropped from 55 to 25 over the past 50 trading days. A VIX score below 18 implied a “risk-on” environment, favoring assets like Bitcoin.  Peterson’s model, which had a 95% tracking accuracy, predicted a $135,000 target within the next 100 days if the VIX remains low. This aligns with Bitcoin’s sensitivity to market sentiment, as a low VIX reduces uncertainty, encouraging investment in ri…

Bitcoin (BTC) rose to an over two-month high of $97,300 last seen at the end of February, before the “Liberation Day” tariffs announcement in the US, bolstering analyst predictions for a rally driven by “structural” institutional and exchange-traded fund (ETF) inflows into the world’s first cryptocurrency. Risk appetite continued rising among crypto investors, as Chinese state-linked news outlets indicated that the Trump administration has quietly contacted Beijing to discuss tariff reductions.

Bitcoin’s (BTC) tight consolidation resolved in favor of the bulls with a break above the $95,000 barrier on May 1. The bulls are trying to push the price to the psychologically crucial level at $100,000, which may again witness a tough battle between the bulls and the bears.  Veteran trader Peter Brandt sounded positive when he said in a post on X that Bitcoin could rally to the $125,000 to $150,000 range by August or September 2025 if it manages to regain its broken parabolic slope. However, Brandt cautioned that the rally could be followed by a sharp correction of more than 50%. Crypto market data daily vie…
    Why Grayscale’s Bitcoin Trust still dominates ETF revenue in 2025
    In the annals of financial history, few institutions have faced the tempests of competition with the steadfast resolve of Grayscale Bitcoin Trust (GBTC). Born in 2013 as a private placement, GBTC pioneered regulated Bitcoin investment, granting investors access to Bitcoin’s (BTC) meteoric rise without the perils of digital wallets or unregulated exchanges. On Jan. 11, 2024, it transitioned into a spot Bitcoin ETF following a landmark victory against the SEC. This marked a pivotal moment with the SEC’s view that ETFs can offer lower expense ratios and enhanced tax efficiency compared to traditional funds.  Even still, GBTC’s financial resilience shines, generating $268.5 million in annual revenue, surpassing the $211.8 million of all other US spot Bitcoin ETFs combined, despite losing over …
    Bitcoin is a matter of national security — deputy CIA director

In an appearance on the market analyst and investor’s show, Ellis told Pompliano that the intelligence agency works with law enforcement to track BTC, and it is a point of data collection in counter-intelligence operations. Ellis added: "Bitcoin is here to stay — cryptocurrency is here to stay. As you know, more and more institutions are adopting it, and I think that is a great trend. One that this administration has obviously been leaning forward into." "It's another area of competition where we need to ensure the United States is we…

Instead of an open and accessible global information system, the web is controlled by centralized global data conglomerates, which don’t just restrict free speech but also monetize your data as a price of entry. Web2 firms have built walled gardens with massive information asymmetry between companies and users. Blockchain-based decentralized tech challenges the status quo, offering an alternative to Web2’s closed-source infrastructure.  It enables developers and engineers to build a censorship-resistant and accessible open-data web to champion the cause of free speech. Open-source technology creates a paradigmatic shift in a fair and inclusive internet where centralized web companie…
    Ether more ‘like a memecoin,’ says trading firm as ETH drops 45% YTD
    As Ether’s price has struggled in the first quarter of 2025, a US-based investment adviser firm, Two Prime, has dropped support for ETH and adopted a Bitcoin-only strategy. After lending $1.5 billion in loans both in Bitcoin (BTC) and Ether (ETH) over the past 15 months, Two Prime decided to ditch ETH to focus solely on BTC asset management and lending, the firm announced on May 1. “ETH’s statistical trading behavior, value proposition, and community culture have failed beyond a point that is worth engaging,” Two Primes stated. The firm’s shift to a Bitcoin-only approach comes as ETH has lost 45% of its value year-to-date, with some optimists speculating that ETH is potentially close to the bottom and reversing its negative trend soon. “Ether no longer trades predictably” “As an algorithmi…
    Moon soon? XRP's strongest spot premium aligns with 70% rally setup
    Key takeaways: XRP’s strongest spot premium phase suggests real buying demand, not just speculative futures trading. The number of XRP addresses holding ≥10,000 tokens has steadily climbed, even during recent price pullbacks. A falling wedge pattern points to a possible breakout toward $3 to $3.78, with up to 70% upside if confirmed. XRP (XRP) is experiencing its strongest sustained phase of spot premium in history, a period where the spot market has been consistently trading at stronger levels compared to perpetual futures. XRP’s 350% rally is backed by real demand Since 2020, most major XRP price peaks happened when the perpetual futures market was leading, noted market analyst Dom in his May 2 post on X. XRP’s futures prices being higher than spot signaled excessive speculation…
    Bitcoin unsure as recession looms, US-China tariff talks kick off
    Bitcoin’s recovery to its all-time high may be threatened by rising recession fears, which could ease if the United States and China begin tariff negotiations this month, research analysts told Cointelegraph. Appetite for global risk assets such as Bitcoin (BTC) may take another hit, with analysts from Apollo Global Management predicting a recession by the summer. “Apollo predicting Summer Recession: Sharpest decline in earnings outlook since 2020,” cross-asset analyst Samantha LaDuc wrote in an April 26 X post. The progress on the tariff negotiations may be the most significant factor impacting a potential recession and Bitcoin’s price trajectory, according to Aurelie Barthere, principal research analyst at crypto intelligence platform Nansen.

    UK regulator moves to restrict borrowing for crypto investments
    The United Kingdom’s financial regulator, the Financial Conduct Authority (FCA), plans to stop retail investors from borrowing money to fund their crypto investments. According to a May 2 Financial Times report, the ban on borrowing to fund crypto purchases is one of the upcoming crypto rules by the FCA. David Geale, FCA executive director of payments and digital finance, told the FT that “crypto is an area of potential growth for the UK, but it has to be done right.” He added: “To do that we have to provide an appropriate level of protection.” Geale denied claims that the FCA is hostile to the crypto industry. Instead, he explained that he views the industry as offering high-risk investments with less consumer protection. “We are open for business,“ he said. The interview follows the FCA …
    Are Donald Trump’s tariffs a legal house of cards?
    On Wednesday, speaking from the White House, US President Donald Trump suggested that families scale back on gifts this year. Asked about his tariff program, the president remarked, “Somebody said, ‘Oh, the shelves are gonna be open. Well, maybe the children will have two dolls instead of 30 dolls, and maybe the two dolls will cost a couple of bucks more.’” But the toy stores where those dolls are sold might have something to say about it.  Earlier in the week, Mischief Toy Store in St. Paul, Minnesota joined a growing number of American small businesses suing the president over his emergency tariff plan. Throughout April, a groundswell of lawsuits led by 13 states further challenged Trump’s ambitious tariff program. Their success or failure rests on hundreds of years of judicial policy an…
    KuCoin to reenter South Korea after securing key markets: CEO
    Crypto exchange KuCoin said that it may reenter South Korea after its platform was blocked in the country.  On March 21, South Korean regulators ordered Google Play to block access to exchanges that were not compliant with the requirements needed to operate in the country. On April 11, South Korea’s Financial Services Commission (FSC) ordered the Apple Store to block unregistered crypto exchanges.  KuCoin was among those affected by the country’s crackdown on unregistered platforms that were previously available. While the platform is now unavailable to South Koreans, it has not fully abandoned the jurisdiction.  In an exclusive interview with Cointelegraph, KuCoin’s newly appointed CEO, BC Wong, said that the crypto exchange has plans to reenter the country.  Wong (left), KuCoin EU CEO Ol…
    European Union to ban anonymous crypto and privacy tokens by 2027
    The European Union is set to impose sweeping Anti-Money Laundering (AML) rules that will ban privacy-preserving tokens and anonymous cryptocurrency accounts from 2027. Under the new Anti-Money Laundering Regulation (AMLR), credit institutions, financial institutions and crypto asset service providers (CASPs) will be prohibited from maintaining anonymous accounts or handling privacy-preserving cryptocurrencies, such as Monero (XMR) and Zcash (ZEC). “Article 79 of the AMLR establishes strict prohibitions on anonymous accounts [...]. Credit institutions, financial institutions, and crypto-asset service providers are prohibited from maintaining anonymous accounts,” according to the AML Handbook, published by European Crypto Initiative (EUCI). The AML Handbook. Source: EUCI The regulation is pa…
    Circle’s Refund Protocol, explained: Bringing refunds to stablecoin payments
    Why are refunds important in stablecoin payments? Anyone who has used traditional payment systems will likely be familiar with refunds and chargebacks. If a purchase goes wrong, like receiving damaged items or not receiving the product at all, the payer can file a complaint with the seller to recover their funds. This process of refunds builds trust between payers and sellers, ensuring secure transactions for both sides. However, stablecoin transactions differ significantly. Unlike credit cards or PayPal, stablecoin payments are generally irreversible. Once sent, the payment is final, with no standard way to dispute or reverse it if issues arise, which can make payers wary of using stablecoins for daily purchases. This highlights the importance of …
    Bitcoin hodler unrealized profits near 350% as $100K risks sell-off
    Key points: Bitcoin long-term holders are about to hit a level of unrealized profit, which has traditionally caused them to sell. That level coincides with the return to a six-figure BTC price. Order book data suggests that bulls may not succeed in keeping the upside going. Bitcoin (BTC) risks a “notable increase” in selling from its older investors if price rises further, warns onchain analytics firm Glassnode. In the latest edition of its regular newsletter, “The Week Onchain,” researchers calculated that long-term holders (LTHs) are sitting on almost 350% unrealized profits. Bitcoin sell-side odds in line for crucial test Bitcoin at multimonth highs will tempt an increasing number of hodlers to take profits — including so-called “diamond hands.” Using a variety of metrics to track i…
    Movement Labs suspends co-founder following MOVE market turmoil
    Movement Labs confirmed the suspension of its co-founder, Rushi Manche, following controversies over a market maker deal that he brokered. Movement announced the suspension of Manche in a May 2 X post, explaining that the “decision was made in light of ongoing events.” The decision follows Coinbase's recent decision to suspend the Movement Network (MOVE) trading, citing the token’s failure to meet its listing standards. Source: Movement The suspension came after a recently announced third-party review requested by the Movement Network Foundation into an agreement orchestrated by Manche with Rentech — the latter helped broker an agreement with market maker Web3Port. Private intelligence firm Groom Lake is conducting the investigation. This was followed by Web3Port reportedly selling the 66 …

    Stablecoins: Depegging, fraudsters and decentralization
    Opinion by: Merav Ozair, PhD Lately, stablecoins are everywhere — this time around, headed by “traditional” financial institutions. Bank of America and Standard Chartered are considering launching their own stablecoin, joining JPMorgan, which launched its stablecoin, JPM Coin — rebranded as Kinexys Digital Payments — to facilitate transactions with their institutional clients on their blockchain platform, Kinexys (formerly Onyx).  Mastercard plans to bring stablecoins to the mainstream, joining Bleap Finance, a crypto startup. The aim is to enable stablecoins to be spent directly onchain — without conversions or intermediaries — seamlessly integrating blockchain assets with Mastercard’s global payment rails.  In early April 2025, Visa joined the Global Dollar Network (USDG) stablecoin cons…
    Artificial general intelligence (AGI): Can it really think like a human?
    What is AGI? When the lines blur between man and machine, you’re looking at artificial general intelligence (AGI). Unlike its counterpart, artificial narrow intelligence (ANI), which is the use of AI for solving individual problem statements, AGI represents artificial intelligence that can understand, learn and apply knowledge in a way that is indistinguishable from human cognition. AGI is still theoretical, but the prospect of artificial intelligence being able to holistically replace human input and judgment has naturally attracted plenty of interest, with researchers, technologists and academics alike seeking to bring the concept of AGI to reality.  Yet another strand of prevailing research seeks to explore the feasibility and implications of AG…
    Crypto in ‘gamble mindset’ as memecoin mentions hit YTD high: Santiment
    Online discussions about memecoins have hit a year-to-date high, gaining considerable attention after sentiment cooled earlier in the year, according to onchain analytics platform Santiment.  Two weeks ago, discussions around Bitcoin (BTC) and layer-1 protocols peaked during the market volatility brought on by the Trump administration’s sweeping tariffs. However, that’s since shifted to high market cap memecoins, Santiment marketing director Brian Quinlivan said in a May 1 blog post. “Online discussions about these high-risk tokens have proliferated as traders embrace a gamble mindset, rather than a calculated investment approach,” he said. “This is a telltale sign that traders are increasingly investing based solely on speculation and short-term gains,” Quinlivan added. Online discussions…
    Riot Platforms posts Q1 loss, beats revenue estimates
    Bitcoin miner Riot Platforms reported its highest-ever quarterly revenue, but still posted a loss as mining costs have nearly doubled compared to the same period last year amid efforts to expand its facilities. “We achieved a new record for quarterly revenue this quarter, at $161.4 million,” Riot CEO Jason Les said in a May 1 report for its first quarter 2025 earnings. The company just surpassed Wall Street estimates of $159.79 million by 1%. Riot’s Q1 revenue was a 50% jump compared to the same quarter a year ago. Riot blames “halving event” for expenses The firm reported a net loss of $296,367 over Q1, a 240% decrease from the $211,777 net income it posted in the year-ago quarter. Riot said that the average cost to mine Bitcoin (BTC) over the quarter was $43,808, almost 90% more than the…
    US Treasury wants to cut off Huione over ties to crypto crime
    The US Treasury Department is seeking to bar the Cambodia-based Huione Group from accessing the American banking system, accusing the company of helping North Korea’s state-sponsored Lazarus Group launder cryptocurrency. The Treasury’s Financial Crimes Enforcement Network (FinCEN) proposed on May 1 to prohibit US financial institutions from opening or maintaining correspondent or payable-through accounts for or on behalf of the Huione Group. Huione Group has established itself as the “marketplace of choice for malicious cyber actors” like the Lazarus Group, who have “stolen billions of dollars from everyday Americans,” US Treasury Secretary Scott Bessent said in a May 1 statement. “Today’s proposed action will sever Huione Group’s access to correspondent banking, degrading these groups’ ab…
    SEC files to drop crypto promo case against YouTuber Ian Balina
    The US Securities and Exchange Commission has filed to drop another of its crypto lawsuits, this time its unregistered securities sales case against crypto influencer and YouTuber Ian Balina.  The SEC said in a May 1 joint stipulation with Balina to an Austin federal court that it “believes the dismissal of this case is appropriate,” citing the work of the agency’s Crypto Task Force. The agency didn’t give a reason for wanting to dismiss its case, but said its decision “does not necessarily reflect the Commission’s position on any other case.” Balina told Cointelegraph in March that the SEC had informed him it would recommend the court dismiss the case and claimed the agency’s actions were based on a shift in the agency’s priorities. “Obviously, the new administration is pro-crypto,” Balin…
    Sky pitches ousting Maker token to complete upgrade
    Decentralized finance (DeFi) lending platform Sky has pitched a proposal to finalize its upgrade from Maker by replacing its governance token and enabling staking. The proposal, posted on May 1 to Sky’s decentralized autonomous organization (DAO) forum, would see the Sky (SKY) token take over the Maker (MKR) token as the protocol’s governance token. If the DAO accepts, the change would be slated to take place around May 15 to May 19 and downgrading from SKY to MKR would also be disabled. Sky co-founder Rune Christensen said in response to the proposal that it was a “huge milestone,” which he “fully supports,” and laments that allowing users to downgrade from SKY back to MKR has been a “key limiting factor preventing exchanges from adopting SKY.” “With this change, exchanges are likely to m…
    Kraken tells how it spotted North Korean hacker in job interview
    US crypto exchange Kraken has detailed a North Korean hacker’s attempt to infiltrate the organization by applying for a job interview. “What started as a routine hiring process for an engineering role quickly turned into an intelligence-gathering operation,” the company wrote in a May 1 blog post. Kraken said the applicant’s red flags appeared early on in the process when they joined an interview under a name different from what they applied with and “occasionally switched between voices,” apparently being guided through the interview. Rather than immediately rejecting the applicant, Kraken decided to advance them through its hiring process to gather information about the tactics used. International sanctions have effectively cut North Korea off from the rest of the world, and the country’…
    Kraken finalizes NinjaTrader buy as Q1 revenue jumps 19%
    Crypto exchange Kraken has completed its acquisition of the futures trading platform NinjaTrader and reported its first quarter revenues jumped 19% year-on-year to $471.7 million. Kraken said in a May 1 report that its NinjaTrader acquisition would give its US customers access to the traditional derivatives market, aligning with its plans to expand its offerings and be the go-to platform for all types of trading. NinjaTrader is a registered Futures Commission Merchant with the Commodity Futures Trading Commission. Last month, it rolled out trading for over 11,000 stocks and exchange-traded funds to certain US clients. The deal, which Kraken dubbed the largest ever between a crypto and traditional finance firm, allows NinjaTrader to expand to the UK, continental Europe and Australian market…

    Tether posts $1B in Q1 operating profit, $5.6 billion excess in reserves
    Tether, the company behind the world’s largest stablecoin by market capitalization, has released its financials for the first quarter of 2025, disclosing nearly $120 billion in exposure to US Treasurys and over $1 billion in operating profit. According to Tether’s Q1 2025 financial report, the company’s assets include $98.5 billion in direct US Treasury bills, along with over $23 billion in additional exposure through repurchase agreements and other cash-equivalent assets. Excerpt from Tether’s Q1 2025 financial report. Source: Tether According to the announcement, Tether holds $5.6 billion in excess of reserves for its USDt (USDT) stablecoin, down from $7.1 billion in excess from the last quarter of 2024. The stablecoin has a market capitalization of $149 billion as of May 1. “Circulating supply of USDT grew by approximately $7 billion in Q1, with a 46 million increase in user wallets,” it said. The company's excess capital continues to fund strategic investments, with more than $2 billion allocated in renewable energy, artificial intelligence, peer-to-peer communications, and data infrastructure.  The stablecoin market is broadly dominated by tokens pegged to the US dollar, with USDT and Circle’s USDC holding a combined 87% share. According to the US Treasury’s Q1 2025 report, the market cap for dollar-backed stablecoins is poised to reach $2 trillion by 2028. European Union officials have recently raised concerns about the risks of overreliance on dollar-pegged stablecoins. According to the Bank of Italy, disruptions in the stablecoins market or the underlying bonds could have “repercussions for other parts of the global financial system.” Magazine: Crypto wanted to overthrow banks, now it’s becoming them in stablecoin fight
    Crypto ‘decoupling’ story ends as stocks follow Bitcoin’s rally
    Key takeaways: Despite weak US manufacturing data, Federal Reserve liquidity plans and strong corporate earnings keep equities and crypto afloat. The total crypto market capitalization rose 8.5% since March. Cryptocurrency traders have frequently zoomed in on the need for crypto to show a clear “decoupling” from the stock market, and over the past 10 days, the intraday movements of Bitcoin (BTC) and major altcoins have closely tracked those of the S&P 500, even as trade war developments have dominated market sentiment.

    The crypto trends Animoca Brands is eyeing this year — Token2049
    Animoca Brands is looking at trends in real-world tokenized assets, AI projects, and the gaming sector to invest in and develop, according to Omar Elissar, the company's managing director for the Middle East and the head of Global Strategic Partnerships. In an interview with Cointelegraph's Sam Bourgi at Token2049, Elissar said that stablecoins, real-world asset tokenization, the intersection between AI and crypto, alternative use cases such as decentralized science, and Web3 gaming were all niches the company is exploring. Gaming is "part of our DNA," the executive said before reflecting on the current state of the Web3 gaming industry: "It's gone quiet for some time in terms of less PR, but there's been building in the background. Recently, there have been a few games that have come out …
    Australian election will bring pro-crypto laws either way
    Despite reports in February suggesting that 2 million pro-crypto voters could decide the outcome of this week’s Australian Federal Election, crypto has barely rated a mention during the campaign. “I think it’s a missed opportunity,” Independent Reserve founder Adrian Przelozny told Cointelegraph. “Neither side has made crypto a headline issue because they’re wary of polarizing voters or sounding too niche.” But the good news is that after more than a decade of inaction, both the ruling Australian Labor Party (ALP) and the opposition Liberal Party are promising to enact crypto regulations developed in consultation with the industry. In April, Shadow Treasurer Angus Taylor promised to release draft crypto regulations within the first 100 days after taking office, while the Treasury itself h…
    Mango Markets exploiter sentenced to over 4 years on child abuse material charges
    Avraham Eisenberg was sentenced to more than four years in prison on child sexual abuse material charges, unrelated to his role in the 2022 exploit that drained the decentralized exchange Mango Markets of roughly $100 million. According to reporting from Inner City Press, a judge sentenced Eisenberg to 52 months in prison at a May 1 hearing in the US District Court for the Southern District of New York. The case was filed in April 2024 after Eisenberg’s 2023 indictment on fraud for the Mango Markets exploit. Eisenberg was initially scheduled to be sentenced in July 2024 following his guilty plea on the child porn charge. In May 2024, the judge suggested the sentencing for both cases would occur simultaneously in a consolidated proceeding. However, as of May 1, the fraud sentencing remains …
    Strategy touts 14% YTD Bitcoin yield in Q1 earnings print, misses estimates
    Update (May 1, 11:35 pm UTC): This article has been updated to add Strategy’s revenue, net loss and analyst estimates. Michael Saylor's Bitcoin-buying firm Strategy, formerly MicroStrategy, has reported earning a year-to-date yield of 13.7% on its Bitcoin holdings as it missed Wall Street's first-quarter estimates. The company said in its May 1 earnings statement that its year-to-date Bitcoin (BTC) yield equates to a gain of more than 61,000 BTC, worth approximately $5.8 billion. Bitcoin yield and gain are unofficial accounting metrics Strategy uses to benchmark the success of its BTC buys.  Strategy’s chief financial officer, Andrew Kang, said it would increase its Bitcoin yield target for this year to 25% and its Bitcoin gain target to $15 billion.

    US lawmaker proposes crypto ATMs in federal buildings

In a May 1 letter to Stephen Ehikian, the acting administrator of the General Services Administration (GSA) — the entity responsible for managing the US government’s properties — Rep.

He requested that the GSA begin exploring the necessary guidelines and regulations needed to install such ATMs in government-controlled properties across the US, citing alignment with President Donald Trump’s goals.

    Institutional Bitcoin buying may soon price out retail — LONGITUDE panel
    Retail investors are running out of time to accumulate Bitcoin as institutional adoption accelerates, according to Sergej Kunz, co-founder of exchange aggregator 1inch. Bitcoin (BTC) is evolving into an alternative reserve currency, propelling institutional demand and potentially pricing out retail investors, Kunz said during Cointelegraph's LONGITUDE event in Dubai.  "Every retail user should be thinking about getting at least one Bitcoin — very soon they won’t be able to afford it,” Kunz said.  If the United States starts buying Bitcoin for a strategic reserve, even smaller countries may soon struggle to acquire the cryptocurrency, he added. "I’m pretty sure we’ll soon see countries battling over who owns more Bitcoin. The US will start.” Bitcoin demand has accelerated since US Presiden…

    Tether CEO defends decision to skip MiCA registration for USDT
    Paolo Ardoino, CEO of stablecoin issuer Tether, addressed criticism over the company's decision not to seek registration under the European Union’s Markets in Crypto-Assets (MiCA) framework, arguing that the regulations were risky for stablecoins. Speaking to Cointelegraph at the Token2049 conference in Dubai, Ardoino reiterated that Tether had no plans to apply for its US dollar-pegged stablecoin USDt — the largest by market capitalization — to be compliant under MiCA in European countries, potentially forcing exchanges to delist the stablecoin. He added that though crypto firms had to follow regulations, there was a “fear of compliance” among companies in the EU. “[...] MiCA license is very dangerous when it comes to stablecoins, and I believe that is even more dangerous for the small, m…

    Devs introduce Ethereum R1 layer-2 scaling solution
    A group of developers within the Ethereum ecosystem, operating independently of the Ethereum Foundation, have announced Ethereum R1 — a layer-2 (L2) scaling solution for the Ethereum network that does not include a native token. According to the announcement, the project relies entirely on donations, does not have venture funding, and does not have any pre-mined token allocations or a governance token. The project's team wrote in a May 1 X post: "General-purpose L2s should be commodities — simple, replaceable, and free from centralized dependencies or risky governance. Ethereum R1 is our answer to that call — the rollup grounded in credible neutrality, decentralization, and censorship resistance." "Most L2s today are acting more like new L1s than an Ethereum scaling solution — private allo…
    Federal crypto legislation could come with a ‘New York State of Mind’
    Love it or leave it, New York State has been a force in crypto regulation. Ten years ago, the state created the United States’ first comprehensive regulatory framework for firms dealing in cryptocurrencies, including key consumer protection, anti-money laundering compliance and cybersecurity guidelines. In September 2015, the New York Department of Financial Services (NYDFS) issued its first BitLicense to Circle Internet Financial, enabling the company to conduct digital currency business activity in the state. Ripple Markets received the second BitLicense in 2016. Circle and Ripple went on to become giant players in the global cryptocurrency and stablecoin industry. Today, the NYDFS regulates one of the largest pools of crypto firms in the world, and it is often cited as the gold standard…

    The case for enterprise-grade custody solutions
    Opinion by: Vikash Singh, Principal Investor at Stillmark The Bybit hack resulted in the largest loss of funds to cyber hackers by a cryptocurrency exchange in history. It served as a wake-up call for those complacent about the state of security threats in the digital assets space. Everyone must learn the lesson from this heist — enterprise-grade custody solutions require tech to be accompanied by transparency. Unlike many previous incidents, this loss of funds was not due to a faulty smart contract, lost/mismanaged keys or deliberate mismanagement or rehypothecation of user funds, but rather a sophisticated social engineering attack that exploited vulnerabilities in operational security.  This hack differs from earlier eras because it happened to a major global exchange that takes securit…
    Bitcoin to $1M by 2029 fueled by ETF and gov’t demand — Bitwise exec

    Bitcoin yield demand booming as institutions seek liquidity — Solv CEO
    The demand for yield-generating strategies around Bitcoin (BTC) is surging, especially from firms seeking liquidity without liquidating their BTC, according to Ryan Chow, co-founder and CEO of Solv Protocol. During a fireside chat at the Token2049 conference in Dubai on May 1, Chow said institutional interest in Bitcoin yield products has grown exponentially over the past few years. Initially, generating Bitcoin yield was nearly impossible. However, recent innovations like staking via proof-of-stake (PoS) protocols and delta-neutral trading strategies have made this possible. Layer-1 and layer-2 advancements, such as Babylon, have made these strategies more viable. Babylon allows BTC holders to earn yield on their assets, which are used to provide security and liquidity for PoS networks. “…

    $21B tokenized RWA market doubtful, institutions uninterested — Plume CEO
    Amid the intensifying global race to tokenize real-world assets, the market is still too nascent for institutional adoption, according to Chris Yin, the co-founder and CEO of Galaxy-backed RWA platform Plume. Institutional capital is yet to enter the RWA market, and it will take some time for institutions to see its value, Yin told Cointelegraph on the sidelines of Token2049 in Dubai. “These things move incredibly slowly, you have to show value, you have to show adoption first,” Yin said, comparing RWA’s currently developing stages with the early days of Bitcoin (BTC) and stablecoins. “Only now, 10 years later, are they beginning to think about using the stablecoin. The same thing is going to happen in tokenized assets or tokenization,” Yin said. Tokenized RWAs are far smaller than $21 bil…

    Robinhood beats Q1 estimates despite revenue, crypto trading dip
    Trading platform Robinhood has still managed to beat Wall Street estimates as its first-quarter revenues fell and its crypto trading volume cooled from a record high in Q4. Robinhood’s Q1 results shared on April 30 show revenues fell 8.6% from the previous quarter to $927 million, topping Zacks analyst estimates by 3.16%. The company’s crypto revenue plummeted nearly 30% quarter-on-quarter to $252 million from the firm’s record-setting Q4 2024.   The drop could be partly attributed to the Trump administration’s tariffs, which triggered an 18% fall in the crypto market cap over the quarter. Crypto trading volume on Robinhood also fell 35% over Q1 compared to the fourth quarter of 2024, which the firm attributed to a 10% drop in customer trades placed and a 27% fall in average notional volum…
    Solana futures open interest nears all-time high — Will SOL price follow?
    Key points: Solana held the $140 support level for a week, a first in more than two months, highlighting traders’ growing confidence. SOL futures open interest hit $5.75 billion on April 30, showing strong institutional interest. With rising DEX volumes and a $9.5 billion TVL, SOL could rally to $200 before a potential spot ETF approval on Oct. 10. Solana’s native token, SOL (SOL), fell 4% between April 29 and April 30 after failing to sustain the $150 level. Despite this short-term decline, traders seem more confident as the $140 support remained intact for a whole week, an outcome that hadn’t happened in over two months.  As demand for leveraged SOL positions reached near record highs on April 30, traders are now reconsidering the chances of a SOL rally above $200. Solana futures agg…

    Mastering Conditional Rendering in React
    What is Conditional Rendering? In React, conditional rendering allows you to dynamically render different UI components based on certain conditions. You can use JavaScript logic such as if statements, the ternary operator (? :), the logical AND (&&), or assign JSX to variables. Using if Statements The simplest way to conditionally render components is by using if statements inside a function component. Example: function AlertMessage({ show }) { if (!show) { return null; } return This is an alert message! ; } export default function App() { return ; } In this example, if show is false, the component returns null and nothing is rendered. Using Ternary Operator (? :) The ternary operator is a compact way to return di…  ( 4 min )

    Cracking MySQL Performance: What is Indexing and Why It Matters
    🚀 Introduction Have you ever run a SQL query that just took forever and wondered, "Why is this so slow?" You're not alone. Databases are fast until they're not. And one of the simplest, yet most powerful performance tricks in SQL is indexing. What indexing really means in MySQL Why indexes are performance game changers The exact results of an experiment we ran on 80,000+ records in MySQL 5.7 on a local setup (8GB RAM, SSD) When indexing helps and when it doesn't Let's dive in. Think of an index like a book's table of contents. If you need Chapter 8, you don't flip through every single page you jump straight to it. That's what MySQL does with an index.

    Welcome to My First Startup Journey
    Hi everyone, After doing my first job as a frontend engineer in a startup for an year, I left my job. Their are multiple reasons for it, but that was the story of another time. After that I decided to not pursue the tech career and start my chocolate factory - HAKI, a chocolate spread idea that crossed my mind.

    Re: Will AI Take My Job? A Coder's Reality Check
    I originally posted this post on my blog. Anita asked if AI, given all the hype, will take her job. Here: Will AI Take My Job? Anita Olsen ・ Apr 22 #discuss #ai Sure, we code daily and AI shines at spitting out code. But most of our work is balancing expectations and handling risk. Apart from coding, we as coders have to deal with: Inter-team planning Brainstorming sessions Putting late sprints back on track Designing requirements and user stories Decomposing a full project into milestones Scoping tasks with Product people Reviewing architecture designs Negotiating deadlines Talking to clients And that involves a lot of human interaction. It shouldn't surprise anyone that a coder will spend more time in meetings than coding on a normal day. And AI can't replace that human interaction yet. But sure, our job as coders will change. Even if we're skeptical about AI, we can't ignore it. We can only assume AI will generate code faster and cheaper than any of us. We have to adapt. We won't be code monkeys anymore, cracking lines of code in exchange for bananas. AI will handle that. And if AI will change everything, let it at least kill dumb SCRUM ceremonies.

    Ethereum bulls show interest as traders’ confidence in ETH’s $1.8K level improves
    Key takeaways: Traders remain cautious about ETH’s price action, but optimistic sentiment is beginning to return. The May 7, Ethereum Pectra upgrade could boost investor sentiment, but ETH’s price action shows investors are still hesitant to open new positions. Ether (ETH) has been trading below $1,900 since March, leading investors to question whether the failed attempt to reclaim $4,000 in December 2024 signaled the end of an era for the leading altcoin. Concerns continue to mount as derivatives market data shows that professional traders remain cautious about ETH’s price outlook.  ETH monthly futures should trade at a premium of 5% or more compared to spot markets to compensate for the longer settlement period, but this indicator has held below the neutral threshold. Ether 3-month fu…

    Binance co-founder and former CEO Changpeng “CZ” Zhao took the stage at Token2049 in Dubai, United Arab Emirates (UAE), where he told the audience that his investment in social media platform X was aimed at protecting freedom of speech. The former Binance executive joined a fireside panel with macroeconomic analyst Raoul Pal to discuss the rationale behind his 2022 investment in X and artificial intelligence. Zhao said: "I think freedom of money is important, but to have freedom of money, you have to have freedom of speech. Freedom of speech is kind of the bottom line. If you don't have that, nothing — no other freedom — works."   "So, when we invested in Twitter back then, it was based on that philosophy," Zhao continued. The former Binance CEO also criticized Europe's crypto policies, ch…
    Bitcoin rebounds from bearish US GDP data as dip buyers push BTC price back toward $95K
    Key takeaways: Bitcoin bulls are attacking the $95,000 level again after today’s brief US GDP-induced sell-off. Traders are semi-agnostic to negative US economic data as they expect the Federal Reserve to resume easing and rate cuts at some point in the future. Bitcoin (BTC) price knocks on the door of $95,000 after starting the NY trading session with a slight sell-off to $92,910 following alarm-raising US GDP data, which showed the economy shrank in Q1 2025. The move mirrors a similar recovery seen in the DOW and S&P 500, which bounced 0.35% and 0.15% respectively at the closing bell.  The quick recovery in Bitcoin price highlights the strong bid by a variety of market participants, and it lines up with the view that the April 30 GDP data could be a one-off event resulting from bus…
    Bloomberg Intelligence boosts Solana ETF approval odds to 90%
    Bloomberg Intelligence has boosted its estimated odds of US regulators approving a Solana exchange-traded fund (ETF) in 2025 to 90%, according to an April 30 post on the X platform.  The company also set more favorable chances of approval for other altcoin ETFs, including proposed funds holding XRP (XRP) and Dogecoin (DOGE), Bloomberg analyst Eric Balchunas said in an X post.  The estimates reflect an improved outlook from Bloomberg analysts. In a February analysis, Bloomberg pegged the odds of a Solana (SOL) ETF approval at only 70%. They ascribed a 65% and 75% chance of approval to funds holding XRP and DOGE, respectively.  As of April 30, six asset managers — including Grayscale, VanEck and 21Shares — are awaiting clearance from the US Securities and Exchange Commission (SEC) to list ET…
    Coinbase files brief with US Supreme Court in support of taxpayers' privacy
    US-based cryptocurrency exchange Coinbase has filed an amicus brief in the country’s Supreme Court in support of a taxpayer fighting the Internal Revenue Service (IRS) gaining access to his data from a digital asset platform. In an April 30 filing in the Supreme Court of the United States (SCOTUS), lawyers for Coinbase argued that a First Circuit Court of Appeals decision set a “dangerous precedent” for crypto users, potentially allowing the government to “trace users’ every crypto transaction in the past and monitor every crypto transaction in the future.” The appeal to the Supreme Court stemmed from petitioner James Harper, a Coinbase user, who took legal action against the IRS after the crypto exchange was forced to turn over transaction data to the government using a sweeping “John Doe…
    Stablecoins on track for $2T market cap by 2028 — US Treasury
    US Dollar-pegged stablecoins are on track to reach an aggregate market capitalization of approximately $2 trillion by 2028, according to the United States Department of the Treasury’s Q1 2025 report. Stablecoins’ cumulative market cap currently stands at roughly $230 billion, but “[e]volving market dynamics [have] the potential to accelerate stablecoins’ trajectory to reach ~$2tn in market cap by 2028,” the Treasury said in the April 30 report.  A stablecoin is a cryptocurrency whose value is pegged to a traditional asset like the US dollar. According to the report, such tokens are already “ubiquitously utilized as ‘cash on-chain,’ effectively serving as a new payment mechanism.” Additionally, the emergence of “tokenized [money market funds] has recently created an alternative option to …
    3 Ethereum charts flash signal last seen in 2017 when ETH price rallied 25,000%
    Key takeaways: Ether price printed a rare monthly Dragonfly doji candlestick, which is often seen before major ETH bull market cycles. ETH is retesting its long-term parabolic support zone that preceded its historic 2017 rally. The MVRV Z-Score has entered the accumulation zone, signaling undervaluation. Ethereum’s native token, Ether (ETH), is flashing a combination of technical and onchain signals once seen in the early stages of its 2017 bull run, a cycle that produced over 25,000% gains. Dragonfly doji hints ETH bulls are regaining control Ether is flashing a rare Dragonfly Doji candlestick on its monthly chart, the same structure that preceded its historic 25,000% rally during the 2017 bull cycle. This pattern is confirmed when the price prints a long lower wick, little to no uppe…
    CZ aims to teach 1 billion kids through Giggle Academy — Token2049
    Binance co-founder Changpeng “CZ” Zhao wants to provide free education for up to a billion children worldwide with his Giggle Academy venture, he told an audience at Token2049 in Dubai, United Arab Emirates (UAE). "In a few years, I think, I want to teach 100 million or 1 billion kids for free,” Zhao told the audience. Giggle is a free online platform that provides elementary education through gamified lessons. "With the technologies we have today, it's not that hard to make an app that will stick, that's educational, but also glues the kids to the device," the crypto entrepreneur said.

    Bitcoin ‘aging’ chart projects sixfold BTC price rally above $350K
    Key takeaways: Bitcoin’s price increased by sixfold each time its age increased by 40%. If the pattern holds, Bitcoin could rally to $351,046 in 2025. New data highlights a historical pattern that results in Bitcoin (BTC) price increasing by sixfold. Using a logarithmic chart to illustrate the trend from 2011, the model projects BTC price to hit $351,046 in 2025. According to 21st Capital co-founder Sina, the study plots Bitcoin’s price on a log-log graph, showing a linear relationship that reflects predictable long-term growth driven by network dynamics, a behavior characteristic associated with BTC’s limited supply.  Bitcoin 40% age increase-price rise comparison chart.

    Tether plans US stablecoin launch as soon as this year — Report
    Tether plans to launch a stablecoin product in the United States as soon as this year, the stablecoin issuer’s CEO, Paul Ardoino, said in an April 30 CNBC interview. Tether’s flagship stablecoin, USDT (USDT), is already the US dollar’s top “exporter,” Ardoino told CNBC. It has a market capitalization of nearly $150 billion, according to data from CoinGecko.  Now, Tether is preparing to expand into the US market “by the end of this year or early next year, at the fastest,” Ardoino said, adding that the timing depends on US lawmakers’ progress on stablecoin legislation. The stablecoin issuer is working to woo US regulators by proactively collaborating with law enforcement and highlighting USDT’s benefits for the US economy. "We are just exporters of what we believe to be the best product …
    VC Roundup: Funding surge targets confidentiality, tokenization and Web3 infrastructure
    After months of volatility and extreme fear, crypto markets turned a positive corner in the second half of April, highlighting the industry’s big sentiment shift.  For venture capital, it was business as usual, with investors continuing to pour money into promising startups across layer-1 blockchains, infrastructure, real-world asset tokenization (RWA), and Web3 social media. This edition of VC Roundup highlights six notable funding deals from April. Unto Labs raises $14.4M for layer-1 blockchain Blockchain R&D company Unto Labs raised $14.4 million to continue developing its scalable layer-1 network called Thru.

    Ethereum Pectra upgrade goes live next week — Will ETH price rally?
    Key takeaways: ETH price has underperformed its peers during the current bull market, but gas sponsorship could lure developers and traders back to the network. Ethereum’s upcoming Pectra upgrade promises to improve staking efficiency, potentially increasing demand for ETH. Data suggests ETH price bottomed. Will the Pectra narrative reignite bullish momentum? Since 2024, ETH (ETH) has been more of a meme than a market mover. Unlike most of its rivals, ETH still hasn’t reclaimed its all-time high of $4,870 from November 2021, and it regularly underperforms even in the weak altcoin market. Currently, ETH trades at $1,813, down 56% from its local peak in December 2024. Despite the dismal price action, dismissing Ethereum as a relic may be premature. The network continues to evolve, and th…
    Ripple $4B-$5B bid to purchase Circle rejected — Report
    Blockchain payments firm Ripple has reportedly bid up to $5 billion in an effort to acquire stablecoin issuer Circle, but the offer was rejected. According to an April 30 Bloomberg report, Ripple put in a bid of $4 billion to $5 billion as part of an attempted takeover of Circle, which was rejected as being too low. Ripple hasn’t considered whether to make another bid to purchase the stablecoin issuer. The reported acquisition attempt came less than 30 days after Circle applied for an initial public offering (IPO) in the US. Cointelegraph reached out to representatives of Circle and Ripple for comment, but had not received a response from either at the time of publication.

    Price predictions 4/30: BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI, LINK, AVAX
    Key points: Bitcoin’s 7-day volatility is the lowest in 563 days, signaling an impending range expansion. Bitcoin’s breakout above $95,000 could swiftly take it to $100,000 and above. Although the probability is low, traders should remain cautious about a pullback in the near term. Bitcoin (BTC) has been trading in a tight consolidation near the $95,000 level for several days. K33 Research head of research Vetle Lunde said in a post on X that Bitcoin’s 7-day volatility has hit a 563-day low. A range expansion usually follows a low-volatility period. Although it is difficult to predict the direction of the breakout, a tight consolidation just below a crucial resistance increases the likelihood of an upside rally. Several analysts are also optimistic that Bitcoin’s break will occur to th…
    Global demand grows for non-dollar stablecoins, says Fireblocks exec
    Governments outside the US, including Singapore, are increasingly interested in stablecoins not tied to the US dollar, despite their currently limited liquidity, Fireblocks director of policy Dea Markova told Cointelegraph at Token2049. In an exclusive interview, Markova described the competition with dollar-pegged stablecoins as “all about sovereignty.” She compared the situation to earlier tensions between governments and US payment giants like Visa and Mastercard. “Now we’re seeing the same dynamic with stablecoins — on a smaller scale for now — but they’re definitely emerging as a new arena for sovereign concerns,” she said. According to Markova, dollar-pegged stablecoins operating in the European Union are already "having a massive headache," particularly from central banks. "Even tho…
    Bitcoin selling at $95K is ‘profit-taking pressure test’ but BTC whales are still buying
    Key Takeaways: US GDP shrank -0.3% in Q1, far below +0.3% forecasts, sparking recession fears. Bitcoin faces selling pressure with its spot volume delta dropping $300 million in 3 days. Whales are accumulating BTC, but smaller holders are selling, hinting at profit-taking. Bitcoin’s (BTC) price dropped under $93,000 on April 30, after the US Gross Domestic Product (GDP) data revealed a -0.3% contraction in Q1. While the GDP missed expectations of +0.3%, the GDP Price Index soared to 3.7%—the highest since August 2023.

    Ex-Binance CEO chides Europe over crypto adoption
    Changpeng “CZ” Zhao, the former CEO of crypto exchange Binance, said most European countries were moving “nowhere” in terms of the adoption of digital currencies. Speaking at the Token2049 conference in Dubai on April 30, Zhao said that areas of the United Arab Emirates were “extremely pro-business,” leading to crypto adoption in Dubai, while others like Bhutan were building national Bitcoin (BTC) and Ether (ETH) stockpiles. According to Zhao, the US was pressing other countries’ hands by exploring its own policies for a crypto reserve, but those in Europe didn’t seem to be reacting. “I don’t see Europe in this discussion,” said Zhao, highlighting one exception. “Montenegro is actually quite pro-crypto. We had an active dialogue with [the] prime minister there, and he’s a very forward-thin…

    Bitcoin drops under $93K after US GDP data shows shrinking economy, raising recession alarms
    Key points:  US GDP shrank in Q1, raising recession alarms while also prompting calls for Fed rate cuts. Bitcoin dropped to $92,910 as GDP figures were released, but sustained buy-side demand could provide support.  Today’s crypto derisking is likely transitory; market fundamentals remain strong. Bitcoin (BTC) price took an abrupt tumble as data showed the US gross domestic product (GDP) retracting by 0.3% in Q1, raising alarms among analysts anticipating a recession. Following the news, BTC price dropped to an intra-day low of $92,910, while the DOW and S&P 500 fell by 1% and 1.3% respectively.  While the GDP figures are shocking at face value, CNBC pointed out that the drop was primarily due to “a surge in imports ahead of President Donald Trump’s tariffs.” Imports are subtracted fro…
    EU digital product passports won’t solve food fraud, but blockchain can
    Opinion by: Fraser Edwards, co-founder and CEO, Cheqd Brutal honesty has its place, especially when confronting discomfort, so here’s one that can’t be sweetened with honey: 96% of imported honey in the UK is fake! Tests found that 24 of 25 jars were suspicious or didn’t meet regulatory standards.  Self-sovereign identity (SSI) can fix this.  The UK Food Standards Agency and the European Commission both urge reform to tackle this concern by creating a robust traceability database within supply chain networks to ensure consumer transparency and trust. Data, however, is not the problem. The issue is people tampering with it.  This is not the first time products have been revealed to be inauthentic, with the Honey Authenticity Network highlighting that one-third of all honey products were fak…
    Bitcoin price recovers, Ethereum RWA value up 20%: April in charts
    April 2025 witnessed crypto markets rocked by more tariffs at the direction of US President Donald Trump — controversial policies that could have influenced the outcome of Canada’s elections on April 28. On April 2, Trump levied “discounted reciprocal tariffs” on 185 countries and territories. The Dow Jones Industrial Average dropped 2,200 points on April 4, while the S&P 500 dropped nearly 6%, its largest decline since March 2020. Bitcoin (BTC) went along for the ride but broke from stocks as it recovered toward the end of the month.  Blockchain adoption metrics for Ethereum are looking good, as the network now boasts 60% real-world asset (RWA) tokenization value. Major firms like BlackRock are sure the blockchain will be the standard for RWAs, but other observers believe that scaling is…

    $330M Bitcoin social engineering theft victim is elderly US citizen
    An elderly US individual is reportedly the victim of a devastating $330 million Bitcoin heist, now ranked as the fifth-largest crypto hack in history. The attacker used advanced social engineering tactics to gain access to the victim’s wallet, onchain investigator ZachXBT said in an April 30 update on X. The hack took place on April 28, 2025, when ZachXBT flagged a suspicious transfer involving 3,520 Bitcoin (BTC), valued at $330.7 million. Following the transfer, the stolen stash was quickly laundered through over six instant exchanges and swapped into privacy-focused cryptocurrency Monero (XMR). Onchain data shows that the victim had held over 3,000 BTC since 2017, with no prior history of large-scale transactions. ZachXBT confirming the victim of the hack. Source: ZachXBT Once stolen, t…
    The open source debate: Is crypto losing its soul?
    Crypto was born from an open-source ethos, where code was shared publicly, accessible for review and shaped by community contributions. Transparency and verifiability are foundational principles that enable trust in Bitcoin. But as the space matured, some disadvantages of open source surfaced. Innovative smart contract platforms and decentralized finance (DeFi) applications were forked to create direct competitors — from the wave of Uniswap clones to Ethereum forks — which prioritized speed and lower fees over decentralization. As a result, some projects opted for closed-source development to protect proprietary designs and reduce the risk of exploits, hoping to delay or deter malicious actors by making the code harder to analyze. This approach is often criticized as “security through obsc…
    FTX sues NFT Stars and Kurosemi in push to recover tokens
    Bankrupt crypto exchange FTX has filed lawsuits against the non-fungible token marketplace NFT Stars and the blockchain gaming firm Kurosemi, which operates as Delysium, accusing them of withholding tokens they owed. The lawsuits, both filed in the Delaware bankruptcy court, alleged that NFT Stars and Delysium failed to deliver all the tokens paid for by FTX despite repeated attempts to resolve the matter. FTX claimed in an April 28 statement that it made “numerous unanswered attempts” to engage with both firms, and it would be “contacting numerous other token and coin issuers regarding FTX assets and will be filing additional suits against non-responsive parties.” Source: FTX As part of the complaint against Delysium, FTX claimed its defunct trading arm, Alameda Research, paid $1 million …
    BlackRock files to create digital shares tracking one of its money market funds
    Asset manager BlackRock has filed to create digital ledger technology shares from one of the firm’s money market funds, which will leverage blockchain technology to maintain a mirror record of share ownership for investors. The DLT shares will track BlackRock’s BLF Treasury Trust Fund (TTTXX), which may only be purchased from BlackRock Advisors and The Bank of New York Mellon (BNY), the firm said in its April 29 Form N-1A filing with the Securities and Exchange Commission. The money market fund holds over $150 million worth of assets, invested almost entirely in US Treasury bills and cash. BlackRock said that the shares “are expected to be purchased and held through BNY, which intends to use blockchain technology to maintain a mirror record of share ownership for its customers.” Unlike the…
    US Treasury’s OFAC can’t restore Tornado Cash sanctions, judge rules
    The US Treasury Department’s Office of Foreign Assets Control can’t restore or reimpose sanctions against the crypto mixing service Tornado Cash, a US federal court has ruled. Austin federal court judge Robert Pitman said in an April 28 judgment that OFAC’s sanctions on Tornado Cash were unlawful and that the agency was “permanently enjoined from enforcing” sanctions. Tornado Cash users led by Joseph Van Loon had sued the Treasury, arguing that OFAC’s addition of the platform’s smart contract addresses to its Specially Designated Nationals and Blocked Persons (SDN) list was “not in accordance with law.”  OFAC had sanctioned Tornado Cash in August 2022, accusing the protocol of helping launder crypto stolen by the North Korean hacking collective, the Lazarus Group. The agency dropped the pl…
    Strategy’s Bitcoin buys should be ‘super careless’ to pump price — Exec
    Key takeaways: Richard Byworth says Michael Saylor’s Strategy could ramp up its Bitcoin buys by acquiring cash-rich companies and converting their cash into Bitcoin. He says that Strategy should consider accelerating purchases as the Bitcoin supply on exchanges continues to decline. Byworth argues that aggressively increasing Bitcoin holdings would boost Strategy’s mNAV, benefiting shareholders. Michael Saylor’s Strategy should take a more aggressive approach to buying Bitcoin by acquiring companies to use their cash holdings to fund purchases and do away with over-the-counter buys, a crypto executive says. “Saylor’s strategy so far has been the right one,” Syz Capital partner and Jan3 adviser Richard Byworth said on an April 29 podcast. Strategy should try “super aggressive” buying Ho…
    Australia’s finance watchdog to crack down on dormant crypto exchanges
    Australia’s financial intelligence agency has told inactive registered crypto exchanges to withdraw their registrations or risk having them canceled over fears that the dormant firms could be used for scams. There are currently 427 crypto exchanges registered with the Australian Transaction Reports and Analysis Centre (AUSTRAC), but the agency said on April 29 that it suspects a significant number are inactive and possibly vulnerable to being bought and co-opted by criminals. The agency is contacting any so-called digital currency exchanges (DCEs) that appear to no longer be trading, and AUSTRAC CEO Brendan Thomas said they’ll be told to “use it or lose it.” “Businesses registered with AUSTRAC are required to keep their details up to date; this includes details about services that are no l…
    Ledger scammers are sending letters to steal seed phrases
    Scammers are mailing physical letters to the owners of Ledger crypto hardware wallets asking them to validate their private seed phrases in a bid to access the wallets to clean them out. In an April 29 X post, tech commentator Jacob Canfield shared a scam letter sent to his home via post that appeared to be from Ledger claiming he needed to immediately perform a “critical security update” on his device.  The letter, which uses Ledger’s logo, business address, and a reference number to feign legitimacy, asks to scan a QR code and enter the wallet’s private recovery phrase under the guise of validating the device. The letter threatens that “failure to complete this mandatory validation process may result in restricted access to your wallet and funds.” Source: Jacob Canfield A seed phrase, or…

    Labor pain, crypto gain — How weak JOLTS data sets path for Bitcoin price to rally
    Key points: Weak labor and consumer data often precede Bitcoin rallies, leading some analysts to anticipate future economic stimulus programs. Job openings fell to 7.2 million in March versus the 7.5 million forecast and consumer confidence hit its lowest level since January 2021. If past patterns hold, Bitcoin could rally by mid-July and possibly reach $140,000 by October 2025. Macroeconomic conditions have long been seen as a major influence on cryptocurrency prices. Generally, Bitcoin (BTC) and altcoins perform poorly when investors fear that employment and consumer data are weakening.  According to a US Labor Department JOLTS report released on April 29, job openings in March approached their lowest levels in four years. US employers posted 7.2 million vacancies in March, below the…
    Betting markets’ Q1 US GDP forecast flips negative amid tariff turmoil
    Bettors on prediction platforms Polymarket and Kalshi are flipping bearish on the US economy. As of April 29, both platforms are predicting that the US will log an economic contraction during the first quarter of 2025 in an upcoming economic data release. The US has logged positive growth figures every quarter since 2022, and a reversal in that trend could mark the start of a recession. The pessimistic outlook marks a stark sentiment shift for prediction markets, which had recently anticipated a positive US growth report. On April 29, consensus Q1 US growth estimates on Kalshi, a US derivatives exchange, plunged from around 0.5% to -0.4% in less than 24 hours. Meanwhile, Polymarket bettors are setting the odds of a US economic contraction in Q1 at around 70%. On April 28, they still had …

    Bitcoin price still in bargain zone as US jobs report sparks rate cut hopes
    Key Takeaways: Fidelity Digital Assets says Bitcoin is undervalued and the firm holds an optimistic mid-term outlook. The JOLTS report shows a sharp drop in open US jobs, raising investors’ hope for Fed interest rate cuts. According to Fidelity Digital Assets, Bitcoin’s (BTC) mid-term outlook dropped to an “optimism” zone, as the investment firm noted that BTC is trending toward “undervaluation.” As proof, the firm cited the ‘Bitcoin Yardstick’ metric, which measures BTC’s market cap divided by its hashrate. A lower ratio suggests that Bitcoin is “cheaper” relative to the energy security of its network. In Q1 2025, the metric stayed between -1 and 3 standard deviations, cooling from its Q4 2024 overheated levels. The number of days above 2-standard deviations dropped from 22 to 15, …

    Indian high court orders steps to block Proton Mail
    A court in India has ordered the encrypted email service Proton Mail blocked in the country for refusing to share information with authorities. In an April 29 hearing of the High Court of Karnataka, Justice M Nagaprasanna ordered the government to “block forthwith” domain names associated with Proton Mail, citing authority under the country’s Information Technology Act of 2008. The order stemmed from a complaint filed in January by a New Delhi-based design firm, alleging that some of its employees received offensive emails through the service.   It’s unclear whether the ban will take effect or face other possible challenges in court. The Proton team reported in March 2024 that Indian authorities had similarly proposed ordering the service blocked in response to alleged “hoax bomb threats,”…

    Bitcoin price always rallies at least 50% after these two patterns emerge
    Key takeaways: Bitcoin tends to rally significantly when low leverage meets stronger-than-expected retail sales and hawkish Federal Reserve signals. In three separate 7-week periods, Bitcoin rose 50% to 84%. Upcoming speeches from Fed Chair Jerome Powell could benefit Bitcoin price. Bitcoin (BTC) price rallies are frequently linked to investors’ inflation concerns or data that surpasses expectations for economic growth, yet clear signals of an impending rally are rare.

    Ethereum’s ‘capitulation’ suggests ETH price is undervalued: Fidelity report
    Key Takeaways: Fidelity Digital Assets’ report said that multiple Ethereum onchain metrics suggest ETH trades at a discount. The BTC/ETH market cap ratio is at mid-2020 levels. Ethereum's layer-2 active addresses hit new highs at 13.6 million. Fresh data from Fidelity Digital Assets hints at a cautiously optimistic outlook for Ethereum, suggesting its dismal Q1 performance could be an opportunity. According to their latest Signals Report, Ether (ETH) dipped 45% during Q1, wiping out it post-US election gains after peaking at $3,579 in January. The altcoin posted a death cross in March, with the 50-day simple moving average (SMA) dipping 21% below the 200-day SMA, reflecting bearish momentum.

    $649B stablecoin transfers linked to illicit activity in 2024: Report
    Cryptocurrency compliance firm Bitrace found that $649 billion worth of stablecoins flowed through addresses classified as high-risk in 2024, according to an April 29 report. Bitrace defines high-risk blockchain addresses as those used by illegal entities to receive, transfer or store stablecoins. Crypto compliance firms typically score crypto wallet addresses based on their likelihood of involvement in illicit activities. The higher the risk, the higher the likelihood of foul play, and the less likely compliant crypto businesses are to accept the assets. Per the report, the amount accounted for roughly 5.14% of all stablecoin transaction volume in 2024. This is down 0.8% from 5.94% the previous year, but significantly higher than the 2.8% reported in 2022 and 1.63% in 2021. Proportion of …

    CBDCs ‘costly fiat copy’, not fintech success so far: Ex-Binance exec
    The United States’ rejection of a central bank digital currency has not halted the progress of CBDCs globally, but their success has been questionable so far, according to a former Binance executive. Global CBDC projects have not failed, but they have also not become what they were anticipated to be, according to Olga Goncharova, CEO at the consulting firm Rizz Go and former director of government relations in the Commonwealth of Independent States at Binance. “CBDCs were conceived as a technological breakthrough, but so far they look like expensive imitations of existing traditional fiat currencies that citizens and businesses already use through online banking and payment apps,” Goncharova told Cointelegraph at the Blockchain Forum in Moscow.

    Trump’s first 100 days ‘worst in history’ despite crypto promises
    The first 100 days of the administration of US President Donald Trump have deeply impacted the crypto industry, starting with his own memecoin and culminating in a Bitcoin reserve and a spate of blockchain policymaking.  Trump’s trade war with the entire world has had the largest short-term impact on crypto markets, as crypto prices have wavered amid macroeconomic worry and uncertainty. Higher prices on electronics mean Bitcoin (BTC) miners are finding it harder to break even, and de-dollarization concerns abound.  Still, crypto markets have shown some resilience and cause for optimism in the administration’s crypto-friendly policies. A number of pro-crypto leaders have been appointed to key government agencies, including the Securities and Exchange Commission and the Commodity Futures Tra…
